DS is 10.5 months and I haven't given him any. The past two ped appointments I forgot to ask her when I could try it and she hasn't mentioned it either. She said she doesn't recommend waiting past a year for allergen foods (like eggs) but I'm not sure about nuts!
My SIL feeds her 8 month old nut butters, but who knows if her ped actually OKed it or not.
Did you wait until a year to give peanut butter?
