My kid showed an allergic reaction the third time he had peanuts, at 6-7 months old. We hadn't lived in much of a bubble up to that point.
You say they live in bubbles, but is that before or after discovering the allergy? After the allergy is discovered, some amount of bubble-ing is necessary due to how difficult it is to be certain than something is peanut-free.
