According to the latest research, cow’s milk allergy is one of the most common food allergies in infants and young children with an estimated prevalence in developed countries ranging from 0.5% to 3% at age 1.
Milk allergy symptoms can appear anywhere from a few minutes after exposure to a few hours after ingesting.
The most common symptoms are rashes, upset stomach, persistent gassiness, excessive fussiness or sleeplessness, and frequent vomiting and/or diarrhea, and blood in the stool.
In babies, a milk allergy may affect their respiratory system. This can cause chronic nasal stuffiness, coughing, wheezing, or difficulty breathing. A cow’s milk allergy may also cause eczema, hives, swelling, itching, or a rash around the mouth and on the chin.
