S.K.
P.,
I had the same reaction with my daughter who was only 1 at the time, they gave her peanut butter at her daycare. Doctor had already told me not to try it until the age of 2 because of my allergies to food. She got hives all over and swelling, Benadryl did the trick, but scared me to death! I didn't give it to her again until about 2 1/2 years, and she didn't ever have another problem, she LOVES the stuff now, at almost 9 years old! I think he will be fine. Just gotta keep an eye out. From my own experiences though, I had severe reactions, to watermelon, almost closed my throat up and had to rush to the hospital and I was about 14 years old then. I went through 5 years of allergy shots and not I can eat about anything, where before almost any fruit I was allergic to.
Good luck to you!
