We have a 4 yr old foster child, who has recently been diagnosed with an allergy to milk proteins. As the doctor put it, it's not going to "kill" her, it'll just make her miserable. She breaks out in hives, and various forms of rashes appear for days. Skin is so clear once we eliminated milk!! I've been told by some, that kids can grow out of this. Is that true? Have any of you had a food allergy that they have grown out of?
