I've read/heard all over that nut & nut products, esp. peanuts, should be avoided until 2 or later because so many children are severely allergic to them. My pediatrician, though, said seafood is the *only* thing you can't give after 12 months (aside from anything they could choke on) for risk of mercury contamination; and that peanut butter is OK to try now (DD is 15 months). I was really surprised about this, though it would be helpful since we don't eat meat (except I eat a little seafood) in our house and it would be good protein & fat. Any experiences in this nut issue? Maybe it was only under 2 + family history of nut allergies I was thinking of?
