Can Infants Outgrow Milk Allergies?


Can infants outgrow milk allergies?

Dr. Greene's Answer

Allergies to peanuts, nuts, shellfish, or fish are usually lifelong.

Thankfully, infants who are allergic to cow’s milk usually do outgrow this. Many will be allergy-free by their first birthdays. The great majority will have no more symptoms by age 3.

Those few that are still allergic after 3 can often still lose their sensitivity — if they are not exposed to cow’s milk for 1 to 2 years.

Of note, at least 30% of kids with cow’s milk allergy are also allergic to soy. Soy allergies are outgrown at about the same pace as milk allergies.
