Cows’ milk protein allergy is one of the most common food allergies in children.
Although cows’ milk protein is one of the most common food allergies in babies and toddlers it can be difficult to diagnose. Cows’ milk protein allergy occurs when a baby’s immune system reacts negatively to the proteins in cows’ milk. If breastfed, the child can react to the cow’s milk protein ingested by the mother and passed to the child through the breast milk. If formula-fed, the child can react to the milk protein in the formula. In both cases the body’s immune system sees these proteins as foreign and in an effort to protect itself, the body releases natural substances, such as histamines, which cause the milk allergy symptoms that your baby might be experiencing.
Cows’ milk protein allergy generally occurs for the first time between the third and fifth month of life in affected children, but the milk allergy can also develop later in life.
