My son outgrew his severe allergy to peanuts, peanut butter, grapes and raisans. He survived schools which did not ban any kind of food allergens. After we discovered his affliction, he didn't suffer again except one time when a young and defiant teen. He decided to have p. butter at a friend's house. He wound up at the ER and never tried that again. Back then there was no mention of epi-pens. Now, my grandson's are updated and he has two with him at all times, though the ER is no more than 5-10 minutes away.
