The doc gave the OK for pb with Mimi at her 12 mo check since there's no family history of any allergies. I gave it to her when she was about 13 mo. It gave her diarrhea. I've also noticed that anything with any trace of peanuts or peanut oil gives her diarrhea.
I'll mention it at her next appointment but, I'm not planning on giving it to her again until she's closer to 3 yo.
