To address one thing a poster said dismissing the "rules" for waiting on having kids try nuts and nut butters: That's not just because of potential allergy problems. It's also because nuts and nut butters have high potential to choke young children. A wad of thick, sticky peanut butter can easily choke a kid. That's also why you should wait on things like popcorn and whole grapes and hot dogs that aren't cut up very small. So the "wait on nut butters and nuts" is important even if the parents think a child won't be allergic; even a kid with no food allergies can still choke.
