Good luck.
I've kept mine alive for nine years. :-) He is at the point where he can self-monitor, although I am still sure to notify other parents at parties or sleepovers so they can be sure not to use peanuts as an ingredient. He has a reaction if he ingests peanuts, but not if he just smells it so we're lucky. He also does not seem to be allergic to peanut oil.
Beware of Chick Fil-A. They cook in peanut oil. Also, chinese food is often cooked in peanut oil. It's really not so hard to eliminate it from your child's diet once you get used to it.
I have heard from some doctors that if it is a mild allergy, they can sometimes outgrow it. Others say peanut allergy is the one allergy that cannot be outgrown.
Who knows. I do know I am NOT gonna be one of those kid in a bubble moms. I have let her eat some candy that said "made in a factory that also processes peanuts", and that caused her no problem. So, on Thanksgiving hubby always fries a turkey, and you have to use peanut oil in those fryers.
Well, my mother, of all people, gave some to my little girl. No reaction. Hmmmm.
So, I am hoping she has a very mild case, and maybe will outgrow it if that is possible.
How did you find out your son was allergic, and have you ever had the actual allergy tests done?
