Earlier quoted context omitted.
No, it's the opposite. The advice we were given was that it was very important that their first encounter with the allergens was to eat them, and not to allow skin contact or anything before that. This meant that with my youngest we had no peanuts in the house until she was old enough to eat solid food, and peanut butter was the first food she ate. It's still her favourite food!
> we had no peanuts in the house until she was old enough to eat solid food That seems like overkill. I can't imagine having peanuts or peanut butter in the pantry is going to meaningfully affect a 2 month old infant.
If you're avoiding skin contact, then you might not have time to wipe the peanut butter mess off your hands as you rush to rescue your kid who's got into trouble.
