Cow's milk allergy

Cow's milk allergy (CMA), also known as cow's milk protein allergy (CMPA), is one of the most common childhood food allergies. It is estimated to affect around 7% of babies under the age of one, but most children grow out of it by the age of five.

CMA typically develops when cows' milk is first introduced into a baby's diet either in formula or when during weaning.
