Allergy to cow’s milk is common in infants and young children and can develop within days to months of birth. The symptoms include abdominal pain, hives, and eczema, and these symptoms are typically associated with immunoglobulin E (IgE) antibodies to milk. Because abdominal pain is also a symptom of lactose intolerance, only your healthcare professional can determine if your baby’s symptoms are caused by an allergic reaction to cow’s milk.
In other children, cow’s milk can lead to colic and sleeplessness, as well as blood in the stool and poor growth. This type of reaction to milk is associated with immune responses that are not related to IgE antibody.
