My pedi suggests 3yo for peanut butter and 6 for whole nuts.
I was planning on waiting until 3 but a few weeks ago my friends fed DD whole peanuts by the handful when I wasn't around (my fault I guess so I didn't tell them NOT to). The next morning they tried to offer her PB toast but I told them no. They have 4 kids and have never heard of anything so crazy

Again, it's like anything, you have to do what you feel comfortable with and of course depends on your LO.
