What to Expect from Baby Poop?

Posted 10.27.09 | Sarah O'Brien

I like to chat with other moms on BabyCenter and lately I’ve seen a lot of questions from parents having to do with baby poop (or the lack of it!). It’s also a popular topic among the calls we get on the Neocate help line. No wonder - when babies have milk allergies and other GI issues, there’s can be a lot going on in that diaper. Every child is different, but here are some general guidelines that we thought might help. Remember, if you have any concerns, it is always best to check in with your doctors.

What to expect if you are:

  • Breastfeeding: If you are breastfeeding your baby, a mustard yellow color is common and it may be seedy and runny. You can also expect to be changing a lot of diapers, because babies usually poop a lot before they reach the one month mark!
  • Formula feeding: Formula fed babies usually have firmer poops, with a peanut butter-like consistency. Normal colors range from brown to green to yellow.

It might be an allergic/GI condition if you see:

  • Mucus – This looks like what comes out of your nose and is sticky when you open the diaper. A little bit can be normal, but if you see a lot and for an extended period of time, it can be a sign of a food allergy.
  • Diarrhea – If your baby is having runnier than normal poops 2-4 times per day for more than 5 days, this is a sign that something is wrong.
  • Blood – Red or black poops can both be a sign of blood in the digestive tract and are often signs of an allergy or uncontrolled reflux.

Note: Remember that some babies’ milk protein allergy exhibits itself in other ways, like eczema, extreme fussiness or reflux. A baby with a milk protein allergy might have just one of these symptoms or any combination of them. If you see any of the symptoms, talk with your child’s pediatrician.

What to expect from an elemental formula (like Neocate):

  • When babies first start on an elemental diet such as Neocate, it may take up to 2-3 weeks for their systems to adjust and have consistent stools. If they seem to be constipated, massaging your baby's belly or moving their legs around can help get things moving.
  • Also, Neocate babies often have poops that can change in consistency and color when they first start on the formula. This is because Neocate is a low residue formula. Low residue formulas lower the number of bacteria in the gut leading to reduced breakdown of bile. More bile is present in the poop making it darker in color.

    My daughter is almost 6 months old and has been mostly breastfed, but we are starting to make the switch to pure Neo-cate.  She now has 1 breastfeed a day.  We introduced a little baby rice for a week and a half and noticed that her poos became thicker and greenish again although there was no mucus.  We have now moved away from rice and onto carrots.  It has become pasty and yellowish-green with bits of carrot in it.  Is this all normal?  I really appreciate any help you can give.

    we started the neocate 2 weeks ago and sometimes it is the dark green poop and sometimes it is yellow and light green. we also noticed even before we started the neocate mucus in the stool and we are continueing to see that.  what is your advice or suggestion on that?

  • 2012-03-21 | Rob

    Hi Megan & Nicole,

    Megan, I’m sorry we didn’t see your comment earlier. What you’re describing is normal. Stool consistency can vary pretty widely, and depends a lot on what you’re little one is consuming. It’s not at all unusual to see bits of food or to see color and consistency changes as you add new foods.

    Nicole - what you describe is also normal. The dark green we hear from almost every parent, and the yellow or tan color can also be common. Lighter colors tend to show up after little ones have been using Neocate for a few weeks. It’s a normal side effect as the body adjusts to Neocate and the digestive tract secretes less bile. For some infants, though, the green color may last for as long as they are on Neocate. Small amounts of occasional mucus are not that unusual, either with or without Neocate. If you have concerns though, or if it seems to be larger amounts of mucus more often, please check with your little one’s health care team.

    Mybson has been on neocate for a week now and he had only two bowel movements the first one was watery and tonight was the second and it was very thick green and foul smelling; it seemed very hard and difficult for him to pass and was cranky and reflux for two days. Can this be the milk still adjusting or is he starting to be constipated from the neocate? B4 this he was staying with very loose and frequent bowel movements that caused him to have a fisher?!!

  • 2012-07-11 | Christine Graham-Garo

    Dear Irena,
    Yes. This could be just the transition stage. We say to give it about 2 weeks to see the body adjust to the new formula. The green color is very typical for Neocate babies, so that is expected. Neocate does nto cause constipation but may reduce the number of stools per day as Neocate is very broken down already. Its always good to keep the Dr informed as well. We are always here to help too if you would like to call and chat with us. Best wishes for your and your son.

    my daughter is 2weeks old and was put on neocate on day 6 of her life her. my son was on neocate for a protien allergy and did great on it. however my daughter seems to be struggling on it she has problem stooling and is projectial vommiting she has been to the hospital to rule out stinosis and blockages I am just curious to know if she could be allegic to neocate

  • 2012-07-23 | Mallory

    Hi Paul,
    It would be very unusual for a baby to have an allergy to Neocate since Neocate does not have any whole proteins. A food allergy is a reaction to the protein component of a food. What makes Neocate unique is the fact the protein is in the form of free amino acids, the form that your body absorbs them as. That being said, I wouldn’t say anything is impossible because we know that every baby is unique. Keep working with her GI doctor and hopefully you can find some resolution soon. Best wishes!

  • 2012-10-18 | Kaleemah

    My son is 3.5 months and has been on neocate since he was about 7-8 weeks. His stool was originally dark green when he first started, and has now changed to a greenish yellow color. It’s very loose & has traces of mucs but not much. Is this normal?

  • 2012-10-19 | Christine Graham-Garo

    Hi Kaleemah,
    This color can be common for Neocate babies. Green is a typical stool color, but we also hear of a yellow-ish color. The very loose stools is something that you should bring up to your Doctor. That isnt common for Neocate babies. We hear about mucous every now and then, but again, discuss with your doctor as the stools should not be very loose. Has the frequency of the stools increased as well?
    Best wishes,

  • 2013-03-22 | Supriya

    My son 10 months started neocate today. He hates the taste and has refused to drink any the whole day. Can I add something to make the taste more appealing. He has had runs(stools/mustard color)around 4 today. Is this common?
    Please Advise

  • 2013-03-25 | Christine Graham-Garo

    Hi Supriya,
    In regards to adding components to the formula to help with taste. Generally we recommend to speak to your Dr before doing so. Being your child is 10m old, it may work well if the Dr agrees. First be sure what you are adding doesn’t contain allergens. We actually wrote a blog on this in the past so feel free to read it.
    In regards to the stool color, we do hear of a mustard or “knaki” color. So this is common to hear of.
    Let us know if any further questions.

  • 2013-06-10 | Rachel

    My son is 10 weeks old and has been on neocate for 1 week. He is consistently having 1-2 stools a day now that are very dark green and very watery? Is it normal for his stool to be this runny on neocate?

  • 2013-06-14 | Mallory

    Hi Rachel- The green color is completely normal. It is also normal for there to be some variation in stool consistency during the transition period to a new formula. If the stools seem excessively watery or if it persists after a few weeks, we’d recommend talking with your son’s pediatrician. Best wishes to you and your little guy!

  • 2013-08-05 | Erika

    My son Ash has been switched from 4 different formulas since birth on Father’s Day of this year. He has been constipated or have had diarrhea. A doctor from the U of M suggested NeoCate to us and even since my son has been eating it, he has had blacker than black super super stain your skin black diarrhea. I’m not sure what to even do anymore. I can’t even breast feed because my body won’t produce enough for him to eat.

  • 2013-08-21 | Fay

    Henry is about five weeks old and we are having a hard time finding the perfect match for his formula. We switched him from Gerber to Enfamil because of constipation and pencil led gray poop. The Enfamil formula gave him diarrhea, but still gray poop. We switched to Nutramigen with iron. This finally changed his poop color to a normal yellow baby poop color. Now he is able to poop 2 to 3 times a day. He’s become a little less fussy, but the diarrhea remains and although he doesn’t spit up every feeding, he throws up every other feeding (more than spit up). He still has stomach pain, probably gas. We are going back to the pediatrician tomorrow. Do you think an amino acid formula vs. a hypoallergenic formula may be the solution?

  • 2013-08-22 | Rob

    Hi Fay,
    The symptoms you’re describing (stomach pain, diarrhea, and frequent spitting up) could be related to a cow milk allergy (CMA). CMA has many possible symptoms, and each L.O. is a little bit different in terms of how they are affected by CMA. That’s not to say that there aren’t other possible factors that could be contributing to Henry’s symptoms. It certainly couldn’t hurt to ask if the pediatrician thinks that CMA may be playing a role, and whether they think a trial of an amino acid-based formula might be worthwhile. Good luck to you all!

  • 2013-09-25 | Dawn

    After five formula changed our son has been on Neocate now for a whie, almost four months. Last week he had mucous in stool, and more frequent stools. We stopped solids a week ago, per the GI for the time being.
    His amount of bms is still increased. He went from every other, or daily to three-five daily. Is an increase of bms normal?

  • 2013-09-26 | Mallory

    Hi Dawn, It sounds like the change in stools might be related to the solid foods and not the Neocate since that is what has changed in the last week. If you are concerned, we recommend getting in touch with the GI doctor to discuss it. Best of luck!

  • 2013-09-26 | LaToya

    My daughter has been on Neocate for almost 2 weeks and her gas is foul smelling along with her tarry poops. What’s the cause?

  • 2013-09-30 | Rob

    Hi LaToya: No two children have the same experience with Neocate. Since Neocate is so broken down, there often isn’t a lot leftover after digestion to come out other end. This often means fewer bowel movements of a different consistency (e.g. soft or pasty), and for some children increased gas. Sometimes the gas improves over time, especially when solids are introduced.

  • 2013-10-13 | cyg

    My 4 month old has been on neocate for almost 2 months. She recently started severe black diarrhea then greenish yellow with seeds and a lot of mucous accompanied with a lot of vomiting. She has been diagnosed with a milk and soy allergy and acid reflux and trachemalacia(sp).

  • 2013-10-14 | Rob

    Hi Cyg: You may want to check with your daughter’s healthcare team. Sudden changes in stool color, consistency, and frequency, along with symptoms like vomiting and diarrhea, can indicate an illness, such as flu. Another factor to consider would be if you introduced anything new to her diet.

  • 2013-11-07 | Tina Precin

    My son has a severe CMA and has been on neocate only for two weeks now. He sees a GI specialist weekly who ruled out internal problems. Since being on neocate his gas is much worse with a severe egg smelling odor. His stool also has the odor. What causes such the foul smell and increased gas? He also spits up every bottle now too even on his Zantac. Thanks.

  • 2013-11-14 | Rob

    Hi Tina: Some parents tell us they do notice strong-smelling gas when their little one is on Neocate, although every infant has a slightly different experience. It can have to do with how the body absorbs Neocate, along with the good bacteria in the gut (which cause gas in the first place!). The spitting up may have to do with how thin Neocate is, since it’s made with amino acids instead of whole protein - you may want to check with the GI to see what they suggest.

  • 2014-02-18 | Tiffanny

    Hi my son is 3 months and has been on neocate since he’s been a month and I notice he still spits up its like gooey to me and when he uses the bathroom it has such a bad smell and it’s like black very watery since we started the neocate could that be normal?

  • 2014-02-18 | Rob

    Hi Tiffany: Most infants do spit up occasionally. For those that have regular reflux after being on Neocate for several weeks, the reflux may not be related to a cow milk allergy. It’s best to check with your LO’s healthcare team to see what they advise. Strong-smelling diapers aren’t unusual with Neocate, but you might check with the healthcare team about the color and consistency (dark green is common, black is not). While every baby’s experience on Neocate is a little different, regularly loose stools and black color could mean more than a milk allergy.

  • 2014-03-09 | jasper

    My 2 weeks old son has changed to neocate, and his stool it’s green, and he only poop once a day,is that normal?

  • 2014-03-10 | Christine

    Dear Jasper,
    Yes, green stool is very typical on Neocate. A slight decrease in the number of stools per day while on Neocate is also expected. If you have any further questions, feel free to ask.
    Kind regards,

  • 2014-05-01 | Ashley

    My daughter has been on neocate for 2 weeks today while I am pumping and dumping. We put her on this because she was super fussy, arching, reflux and horrible mucous in stool. After two weeks she poops twice a day and they are liquid with mucous. The gi specialist said it could take two weeks to heal. Can it take longer? Should I be worried?

  • 2014-05-01 | Mallory

    Hi Ashley,
    We tell parents to give it about two weeks to see improvement. For some babies, it can take a little longer. It really depends on the underlying issue. Other than the loose stools, have you noticed any improvement in her symptoms? If so and it seems like its otherwise helping, then you might wait a little longer to see if her stools normalize. Continue to work with the GI specialist and hang in there! Please give us a call if you have any further questions.

  • 2014-05-23 | Mollie

    My 4 month old son just started Neocate two days ago. Today, he had a very difficult time passing a stool. When it finally did pass, it appeared to be a normal dark green color with a smooth consistency. I was a bit worried when he seemed so uncomfortable. Is this his body adjusting to Neocate? If so, is there anything I can do to ease his discomfort? He was previously breastfed, then enfamil Gentlease, then Nutramigen, and now Neocate. It has been a long road and we are really hoping Neocate is the answer.

  • 2014-05-27 | Christine Graham-Garo

    Dear Mollie,
    In the first couple weeks, there is definitely an adjustment period with any new formula, including Neocate. Its good to keep the Dr informed of his discomfort when passing stool - just to be on the same page. Generally, it is typical, in the first 2 weeks of starting a new formula, to see some gassiness, for example. This should subside with time as his body adjusts to the Neocate. Be sure to mix the Neocate as instructed on the label (unless told differently by your doctor). After 2 weeks, if you are in the same boat, feel free to call us to further discuss (1-800-365-7354, 8:30a-5:00p, Mo-Fri.)
    Best wishes,

  • 2014-06-26 | Aswathy

    My son is on neocate since he is two months old and doing well with this. He was only having bowel movement once in every 3-4 days loose but for past 2 days he is having BM every day same consisitency (green loose). He is only taking same amount of formula as before. I like to know it is normal?

  • 2014-06-27 | Rob McCandlish, RDN

    Hi Aswathy,
    It’s not unusual to see some infants on Neocate with stools more frequently (daily) and others less frequently (every other day or so). The consistency also varies. Because your son had been consistent but has had a change in the frequency and consistency of stools, it would be best to check with his healthcare team. They can tell you if it’s anything unusual.

  • 2014-06-28 | Jamie

    My son has been on Neocate for a couple of weeks now. He was diagnosed with failure to thrive after about four formula changes with no weight gain. He is about 7 weeks old now, and the Neocate seems to satisfy him and he has been gaining weight with 24 calorie feedings. However, he still seems to spit up a lot and have stools almost every diaper change, being the green seed stools which I understand is normal. It is never a pasty consisty, I wouldn’t consider it diarrhea either. Is this normal to have so many stools? And still so a lot of spit up? He has had an upper GI barium swallow, showing everything is working fine. Thanks for your time.

  • 2014-06-30 | Rob

    Hi Jamie,
    When spit up is related to a cow milk allergy, Neocate may help. However, spit up can be unrelated to an allergy, in which case Neocate might lessen spit up frequency slightly or not at all. Some parents do see an improvement, whereas for others the spit up continues unchanged. Check with the healthcare team: for some infants, spit up just takes time to outgrow.
    Stool frequency and consistency is highly variable on Neocate. While most infants have less frequent stools of a pasty consistency, we hear everything! What you’re describing isn’t unusual.

  • 2014-07-29 | Dung Hoang

    My pediatrian and I suspect that my 5 month old baby is having EOE. So we put her on Neocate. After 2 days and a half of taking only Neocate, her symptoms do not go away. She still feels pain while swallowing and after each feeding, her voice sounds hoarse. She gradually refuses to take it. She only take 2 oz or 3 oz maximum and after that her esophagus sound noisy. She only takes about 10 to 12 oz of Neocate the whole day! And after 2 days, it is even going down. How long should I see improvement in my baby? I expect to see improvement after 2 days but it is not. What should I do?

  • 2014-07-30 | rob

    Hi Dung,
      Some parents do notice an improvement very soon after starting Neocate, but often it takes longer for food allergy symptoms to improve. Research suggests it may take up to 14 days, especially with EoE, so most clinicians recommend about 2 weeks to see full improvement. It can also take a few days for some infants to adjust to Neocate, which is pretty typical.
      You should talk to your daughter’s healthcare team for their advice on how long to trial Neocate and guidance on her intake. We do have tips on transitioning to Neocate that you could discuss with them: you can find it here: bit.ly/NeocateTransition
    Best of luck,

  • 2014-11-06 | Jessica

    Hello my daughter switched from Neocate infant to jr after a little over a year. We were getting the neocate poop so I am familiar with that color, but is the neocate jr poop typically that color too or should I expect a change because of the probiotics?

  • 2014-11-10 | Rob McCandlish, RDN

    Hi Jessica,
      For an infant Who’s been on Neocate Infant DHA/ARA and transitions to a version of Neocate Junior (without prebiotics), the stool color and consistency would not be expected to change much, unless something else about her/his diet changes. If she/he switched to a version of Neocate Junior with added prebiotics (a type of fiber), then the color and consistency might change. Neocate Junior with Prebiotics is available in Unflavored, Vanilla, and Strawberry, whereas Neocate Junior without added prebiotic fiber is available in Unflavored, Chocolate and Tropical.
      There are a lot of other factors that can affect stool consistency and color, so if you have additional questions it would be best to ask your daughter’s healthcare team.
      Kind regards,

  • 2014-11-24 | kathryn

    My 4 month old granddaughter rently passed away. She was put on neocate at 1 week and 3 days old. My question is her poop was very very dark green and black the hold time she was on neocate, what could be the cause for this?

  • 2014-11-25 | Rob McCandlish, RDN

    Hi Kathryn,
      We’re so sorry for your loss. Hopefully you can spend time with loved ones this holiday season and celebrate the time you had with your granddaughter.
      It’s very common for an amino acid-based formula to cause stool to be very dark green. It’s a normal side effect of formulas like Neocate, as the body adjusts to Neocate and the types of normal bacteria in the gut change, they break down less bile (which helps digest food). More bile is present in the stool making it dark green in color.
      Please take care,

  • 2014-12-02 | MIchelle

    We just started our daughter on Neocate about a week and a half ago. She also started seeing a chiropractor who recommended a probiotic. I was reading about how Neocate changes the bacteria in her gut. Should she not be on probiotics with this formula? Or are there certain ones she should be on? I don’t want to be counteracting what the formula is doing.

  • 2014-12-03 | Rob McCandlish, RDN

    Hi Michelle,
      Great question! An infant or child consuming Neocate can certainly also take a prebiotic (fiber) or probiotic (“good” bacteria) supplement, or both, as long they have been recommended by the healthcare team. One word of caution if your daughter has a dairy allergy: make sure that it’s a dairy-free probiotic. Many probiotic supplements are cultured using dairy or made or packaged on shared equipment with dairy.
      There are many different probiotics available with different species and strains of bacteria. It’s best to check with the healthcare team to see which one(s) they recommend, based on published evidence and/or brands their practice has seen the best success with.
      Best of luck to you,

  • 2015-02-01 | Kelly

    Hello! My 8 week old just switched to neocate last night and u thought it was a miracle after he gave me 6 straight hours of sleep. However, as if this morning he has been projectile vomiting after every feed. Should I give him some more time to adjust? Is it at all notmal to be vomiting after every feed in the beginning? Thank you!

  • 2015-02-02 | Rob McCandlish, RDN

    Hi Kelly,
      Good question. It’s not unusual for some infants to experience increased reflux when they initially transition to an amino acid-based formula. This can be due to the thinner consistency, the different taste to other formulas, or a combination of the two.
      The best thing to do would be to check with your daughter’s healthcare team for their guidance. Sometimes the team might suggest backing off and doing a more gradual transition, whereas other times they might suggest continuing. They often recommend a 2- or 3-week trial of Neocate to see the full benefits. Best of luck, and call us with any questions at (800) 365-7354.

  • 2015-02-27 | olivia

    My 3 month old has been on neocate for 1 month and she is pooping maybe every 2-3 days and it is a dark green color! Is this normal? Or is there something wrong?

  • 2015-03-02 | Rob McCandlish, RDN

    Hi Olivia,
      What you’re describing is fairly typical. Many infants taking an amino acid-based infant formula have stools less frequently (often ~1 every day or two). The stool is often dark green or hunter green in color (see some of the comments above for the reason). You may see that color as long as she’s on Neocate, or it may become more tan. When you introduce solid foods you’ll probably notice changes in the frequency and color of her stool as well.

  • 2015-03-16 | Kelly

    My son has been on Neocate for about a week now. Before Neocate, he was on Nutramigen for cow milk allergy that gave him diarrhea every diaper change and rashes all over his body and face. Nutramigen still gave him rashes and very watery and loose stool about 3 times every day. Since he’s been on Neocate, his stool is dark green with black spots in it. There seems to be mucus in his stool when I try to smear it around his diaper. He makes bowel movements 1-2 times everyday. Is this normal?

  • 2015-03-17 | Nutrition Specialist

    Hi Kelly,
      What you’re describing doesn’t sound unusual, but you may want to follow up with the healthcare team to be sure. Many infants taking an amino acid-based infant formula have stools less frequently (often ~1 every day or two). The stool is often dark green or hunter green in color (see some of the comments above for the reason). You may see that color as long as she’s on Neocate, or it may become more tan. Small amounts of occasional mucus are not that unusual, either with or without Neocate. If you have concerns though, or if it seems to be larger amounts of mucus more often, please check with your little one’s health care team. Most healthcare teams suggest about a 2-week trial of Neocate to adjust to the formula.

  • 2015-12-09 | Karina

    my baby has projectile vomiting on this, he “poops” every other day and it is not poop it is very watery and about a tablespoon. the peds doc says everything is normal? HOW is this normal? Is this formula not working or he just needs adjustment? do you think there is blockage?

  • 2015-12-10 | Nutrition Specialist

    Hi Karina,
      What you describe isn’t necessarily unusual with amino acid-based formulas, like Neocate. Hence the “normal” description from the pediatrician. Because Neocate is thinner than regular infant formula, some infants spit up more easily until they adjust to it. And bowel movements tend to occur less frequently (once every 1-2 days is typical) and tend to be small, with varying consistency. The healthcare team can advise if they think there are factors other than formula contributing to his symptoms. Best of luck to you!

  • 2016-01-10 | desireedepaola

    Hi, my daughter is 2 months old and has been on 3 different formulas. She just got referred to a GI doctor and they put her on Neocate. She has been on Neocate for 5 days now. The first two days she didn’t have a bowel movement and when she did it was pasty and dark green and had a real foul smell. Now her stools are still dark green and have a foul smell but are watery? Is this normal, is her body still adjusting to the Neocate?

  • 2016-01-11 | Nutrition Specialist

    Hi Desiree,
      What you’re describing doesn’t sound unusual, but you may want to follow up with the healthcare team to be sure. Many infants taking an amino acid-based infant formula have stools less frequently (often ~1 every day or two). The stool is often dark green or hunter green in color (see some of the comments above for the reason). And we often hear about bad smells. Consistency of bowel movements also varies, and is often pasty. If you have concerns though, please check with your little one’s health care team. Most healthcare teams suggest about a 2-week trial of Neocate to fully adjust to the formula.
      Good luck,

  • 2016-05-02 | Stephanie

    My little guy is 7 weeks old and he has suffered with fussiness, gas, and skin issues (which have cleared up a bit now). He would be extremely fussy all day and especially after feedings. My doctor put him on Zantac thinking it might be silent reflux. It got better for a couple of days but then the fussiness has started again. He also said that if it doesn’t work, we will move to Neocate in case it’s an allergy. I am willing to try this but not if his gas is going to get worse. I keep reading people’s experience and the only negatives I’ve heard are constipation and gas. Right now his BM are good consistency and once a day. I don’t want to change that. Could you please help! I don’t want to change him just to make him worse!

    Thank you!

  • 2016-05-03 | Nutrition Specialist

    Hi Stephanie,
      I wish we could guarantee what to expect, but every little one’s experience with amino acid-based formula is unique! When there are changes in gas, they often adjust to them over a few weeks. The fact that Zantac hasn’t been fully successful is an indication that your little guy’s reflux could be due to a food allergy. (That’s not always the case - my nephew was on Neocate and it improved all of his allergy symptoms, but did not fully resolve his reflux, which was not an allergy symptom for him.)
      We’d hope that Neocate would help with his other symptoms. If you’re very concerned about regularity and gas, you can always ask his healthcare team about adding a source of fiber to Neocate. Amino acid-based infant formulas do not have fiber, which is part of the reason that infants who take amino acid-based formula may have fewer bowel movements and changes in gas. Let us know if there’s anything else we can do to help.
      Best of luck!

    My little girl is 6 months old. She had been on nutramigen for about 4 weeks before gp recommended trying her on neocate. She’s been on neocate for 3 days and her poo this morning was slightly firm and dry. Is this common during transition period?? She is having pureed food too. Many thanks

  • 2016-07-06 | Nutrition Specialist

    Hi Leah,
      What you’re describing isn’t unusual. We’ve heard everything in the book, because every baby is unique! Usually infants whose only intake is a hypoallergenic formula like Neocate will have stools that are pasty, but this is variable. Having solid foods in the diet along with Neocate tends to result in more firm stools.

    Hello, I am writing to you from the Czech Republic. Daughter is 5 weeks on Neocate Advance (based on doctor’s diagnosis of milk allergy). Is it normal that the stool is strong-smelling and for her to have severe stomach pain and gas? Thank you for answer.

    Hello Petra,
      It is not unusual for the stools to have a strong smell when a child is consuming an amino acid-based formula like Neocate Advance. (We do not have Neocate Advance in North America, but it is very similar to Neocate Junior.) Many parents also report that there can be a change in gas, such as increased gas, for the first few days or weeks as the child adjusts to Neocate. It is not common, however, to have severe stomach pain, especially after being on the formula for 5 weeks. Please consult your daughter’s healthcare team for their guidance, as it is possible that this is not related to the Neocate.
      Kind regards and best of luck,

    My Twin Sons Of 12 Weeks Are On Neocate Since 3 Weeks…..Elder One Is Pooping Three-Five Times A Day…Mucous In It….Is It Normal..Please Help..And Even Wet Gas Is Passing In His Diaper

  • 2016-08-23 | Nutrition Specialist

    Hi Chandrai,
      Every little one has a slightly different experience with Neocate. It sounds like your sons are a prime example! While most infants on Neocate will have a bowel movement once every day or two, that’s not always the case. And the consistency can vary too, from solid, to pasty, to moist, to mucousy. The best thing to do if you’re concerned is to check with the healthcare team to get their thoughts.
      Best of luck!

    Hi There, my 13 week baby has been diagnosed with dairy allergy and reflux. She’s been on soy formula up until last week I have started weaning her on Neocate Gold.  I have noticed after she’s had a Neocate feed she gets bad tummy pain and gas.  Is this normal? will it get better over time?

  • 2016-08-29 | Nutrition Specialist

    Hi Jennifer,
      It’s not unusual for infants to take a few days, up to 2 weeks, to adjust to a new formula. With Neocate formulas, infants often only have a bowel movement every 1 or 2 days, sometimes less frequently. It’s not unusual to see them strain a bit after feedings with hypoallergenic formulas. Changes in gas are also usual. They usually adjust to the new routine over time. If you have any questions you should check with her healthcare team. They may also have some strategies to suggest to make her more comfortable if she looks upset over the next few days.
      Best of luck!

    Good afternoon, my son is 3 months old going to 4 this month, he’s been taking Neocate for the past 2 months already he’s been drinking it good and doing restroom, sometimes constantly vomiting I believe cause of his reflux.  However, this past few days he been having trouble doing the restroom he get fussy and trouble to go to sleep and at times we have to help him do the restroom. Can Neocate cause sometimes for babies to be constipated?

  • 2016-12-02 | Nutrition Specialist

    Hi Iveth,
      Neocate doesn’t cause constipation, but it’s not unusual for infants who take Neocate to have fewer bowel movements (often one every day or every two days) and the texture is often pasty. This is different for everyone, though. The best thing to do is talk to your son’s healthcare team. Since he had been pretty stable on Neocate, there may be something else that has changed recently that could be affecting him. They may have some suggestions or strategies to help.
      Best of luck to you!

    My breastfed baby is 5 months old, we are on day 4 of a gut rest for MFPI since we still see occasional blood and mucous on a 13 food elimination diet.  My baby is growing, gaining, and happy.  Day 4 of neocate he has horrible reflux, like worse than early days. He’s also pooping more than normal (normal 1 to 2x a day) yesterday was 4 and it’s pretty mucousy.  Is this normal transition stuff? The GI doctor just said “that’s strange” and the pediatrician said to slow the transistion to help him adjust…so 50/50 formula breastmilk.  With that being said, I just want to know if this is a normal transition or if this should be considered a fail.  He is a happy baby and the last 4 days have been awful.

  • 2016-12-12 | Nutrition Specialist

    Hi Amanda,
      What you’re describing is unusual, but certainly not unheard of. Increased spit-up can occur in the early days because amino acid-based formulas like Neocate are thinner than most formulas. And while stool patterns usually settle into only once every day or other day, there may be a transition period where that’s not the case as they adjust.
      In general, the best guidance is that it can take up to about 2 weeks after starting a hypoallergenic formula to 1) see the full improvement in food allergy symptoms that can be expected, and 2) to see what the “new normal” will look like in terms of stool patterns.
      You’ve done the right thing - our guidance is always to reach out to your healthcare team if you have questions. Best of luck!

    On day 5 of Neocate ... my little guy is experiencing 3 stools/day and fairly loose. Does this signify he’s allergic to Neocate too? Diarrhea has never been an issue for him before.m even with suspected. CMA.

  • 2017-02-08 | Nutrition Specialist

    Hi Meghan,
      Not necessarily! With a change in formula, it can take up to 2 weeks to fully adjust to the new formula. Amino acid-based formulas like Neocate are digested and absorbed differently than standard formulas, which can also take some adjusting to. The best thing to do is talk to your son’s doctor, who can also consider whether his symptoms might be related to something else.
      Best of luck!

    My son had been on neocate for almost a week now he is only having one stool a day and he is very gassy is this normal?

  • 2017-02-27 | Nutrition Specialist

    Hi Crystal,
      Yes, that’s fairly typical! Most infants on amino acid-based formulas like Neocate have bowel movements once a day or once every other day, sometimes even less frequently. And changes in gas aren’t unusual either. It may take up to about 2 weeks for your little guy to settle into his new normal.

    Hi, my twin granddaughters were born 4 months prematurely. They are now 8 months old and recently placed on Neocate. Prior to they were on one of the Similac brands and were very constipated. They were placed on milk of magnesia x2 a day. Now that they are on Neocate and receiving milk of magnesia they have severe diarrhea and awful diaper rash. Their butts are tore up! Not sure what to do at this point. Any advice??

  • 2017-03-13 | Nutrition Specialist

    Hi Anna,
      The best thing to do is to check with your granddaughters’ healthcare team. Depending on how long they’ve been on Neocate, the team may want to wait a few days to see how they adjust - the usually guidance is to give up to 2 weeks to adjust to a new hypoallergenic formula. They may also want to explore stopping the milk of magnesia, possibly gradually. Definitely don’t make any changes before you check with the team, though!
      Best of luck,
