K.C.
This is kinda funny that you ask. I'm a mom of 4 and have ALWAYS given my kids peanut butter at 1. It wasn't until my 3 year old was 14 months and I heard you're not supposed to until 2! It's a nut allergy that they're worried about - but you won't find out until you give it to them - whether it's at a year or 5 years!!
I say let her have it and watch her the first time for any signs of allergy. If there isn't any - add it to her menu!
