We were also advised to wait until 3--because dd had MSPI, so even though we don't have any history of nut allergies, we're just supposed to be cautious of all nuts and other high risk allergies (shellfish) until 3. It's not worth the chance.
I'll have to look for the sun butter though--I bet dd would love it, and I always wish we could do sandwiches, but she won't eat meat, and can't have pb, so there isn't much left besides a plain cheese sandwich.
