hi .. my daughter is cow milk allergic since starting but now she is gonna become 4 years old now.. can now we give her cow milk or should we avoid it lifetime?

A. Studies show that most children with non-IgE-mediated reactions will outgrow cows' milk allergy by the time they are 3 years old. For children with IgE-mediated reactions, studies show that about half of these children will outgrow cows' milk allergy by the time they are 5 years old.
