My son has peanut allergy but not as severe. Peanut can touch him with out a problem.
My IRL friends teenage son is so bad that if someone touches food that had been processed in a plant that processes nuts and then touched him (say like m and ms) he will have a reaction.
That being said, until you know what your dealing with... I wouldn't feed your kids anything peanut and would clean all her toys. I would also require friends to wash hands before playing and to avoid eating peanut before coming over. Peanut oil is a bugger because its hard to get off.
