When to Trial Milk?

Posted 9.29.10 | Sarah O'Brien

If you have a child with a milk protein allergy, you’ve probably wondered if they will ever outgrow it. There is a chance your child will eventually develop a tolerance to milk and outgrow their allergy, although it is less likely than previously thought. A study conducted at Johns Hopkins University in 2007 showed that 19% of children outgrew their milk allergy by age 4, 42% had outgrown it by age 8, and 79% were milk allergy-free by age 16.

So how can you tell if your child is no longer allergic to dairy products?

Conducting a Milk Trial

Often your pediatrician or allergist may suggest a milk trial to test their tolerance once your child is over 12 months old and hasn’t had any diary in their diet for at least 6 months. A milk trial typically consists of giving your child a small about of dairy, often starting with products like yogurt or cheese which can be tolerated better than cow’s milk. If your child does not experience any adverse reactions (such as diarrhea, vomiting or gassiness) then you can continue to give increasing amounts of dairy products, slowly working up to 100% cow’s milk.

Milk Trial Precautions

It is important to remember that if your child originally had a severe reaction to milk, such as anaphylaxis, then you should have the milk trial conducted under medical supervision. Do not try re-introducing milk at home! Even if your child had a less severe reaction it is always important to get the go-ahead from your doctor ahead of time, just to be on the safe side.

Failing a Milk Trial

If your child is not able to tolerate the dairy you introduce in the milk trial, this simply means you will need to continue eliminating it from their diet. Your doctor may want to try again with another milk trial in 6–12 months. In the meantime, it is important to make sure that they are getting all of the nutrients they need. One option is to switch them to an elemental toddler formula, like Neocate Junior, which is specially formulated to be nutritionally complete for children 12 months and older with food allergies and related GI conditions.

Have you tried a milk trial with any of your little ones with milk protein allergies? How did they go?

Understanding How Infant Taste Buds Work

Posted 2.4.10 | Mallory West

Ever wonder if your infant has the capacity to really taste his or her food? Well, this post will address the sense of taste in infancy!

To start, let’s review the basics of the “gustatory system”. Taste buds on the tongue relay information to the brain, which is perceived as taste.

The 5 basic tastes of any human are:

  • sweet
  • salty
  • sour
  • bitter
  • savory (aka umami).

Research shows that infants are born with a predisposition to accept sweet tastes, such as breast milk. Infants also have a predisposition to reject new foods, a phenomenon known as “neophobia”[1]. During infancy, almost all foods are “new” so it’s no wonder that introducing a new food or formula may result in some resistance from your baby.

The good news is that this neophobia can be overcome by repeated exposure to the food. In other words, taste preferences aren’t set in stone; they are constantly evolving. With repeated experience, infants accept and may even prefer the previously rejected food. One study observed mothers who presented a particular food daily over a period of time. The researchers found that it took 15 feedings for the infants to accept the new food readily.

Therefore, whether you are introducing solids or switching over to Neocate from another formula, don’t be discouraged! It is not only ok, but normal for your little one to reject the new food at first. Just be patient and persistent and continue to present the food in a positive manner.

An interesting tidbit: An infant’s perception of bitter taste is developed several months after birth. A study found that newborn infants did not reject the taste of bitter, while older infants did[2]. Another study identified the time period for this developmental change to be around 4 months of age[3]. The researchers found that infants who were put on a specialized, broken down formula (which have a slightly bitter taste due to the broken down protein) before the age of 4 months transitioned to the new formula with no resistance.

After this age, the infants identify the change in taste and moms may have to be a bit craftier to transition their little one onto the new formula. The researchers pointed out that a gradual transition, where the new formula is mixed with the previous formula, helps older infants to accept the new formula. This allows infants taste buds to gradually and repeatedly be exposed to the new flavor and associates the flavor with something that they already like (the previous formula).

What tastes did your child prefer when you first began introducing foods? Have you noticed any change in their taste preferences as they get older?
