I have a boy who has almost died twice from ingesting a tiny amount of peanuts. Luckily, he doesn’t react (much) to airborne exposure or to touching peanut. But I purposely slip him food with peanuts in it every once in a while. I am trying to instill in him that he cannot rely on ANYONE to watch out for him. He must read the ingredient lists himself. If he misses it, I make him read it again.
Restaurants are another matter. You can’t rely on what the workers or managers tell you. But my kid can tell by tasting the food. His mouth will burn violently, unless the nuts are in ice cream or something cold. As long as he doesn’t swollow or drink anything afterward, he can wipe out his mouth and avoid going into shock.
Good for you...you sound like a responssible parent who takes on the responsibility of their child. Kudos.
There are some quite specific chemicals that can cause that reaction ~ not just the nut allergy ~
It seems to be a reaction to chemicals associated with the cyanide found in plants.
