Symptom Guide

Unfortunately, infants and very young children cannot use words to tell you what’s wrong. But physical symptoms can speak volumes if you know what you’re looking for.

Symptoms of a milk allergy or milk allergy-related conditions can be as diverse as inconsolable crying, baby rash, diarrhea, vomiting and wheezing. This guide should help you identify symptoms so you can discuss them with your doctor and dietitian.

You can also visit our Food Allergy Glossary for definitions of food allergies and GI-related terms.

Symptom Guide  /  Breathing Symptoms  /  Wheezing


Wheezing is a high-pitched whistling sound made while breathing, usually breathing out (expiration). Wheezing results from narrowed airways.

The most common cause of recurrent wheezing is asthma, but there are many other possible causes of wheezing.  Wheezing can be a sign of a food allerg related reaction.
