Young children often outgrow their food allergies, especially to soy, wheat, egg, and milk products. It is less likely that a child will outgrow peanut allergy. However, studies during the past few years have indicated that about 20 percent of children with allergic reactions to peanut in the first years of life may eventually outgrow their sensitivity. Children with food allergies should see their allerfist at least annually to reevaluate their allergies.
