Peanut butter is safe for babies but can be very dangerous for those with peanut allergies. The problem is that you will not know if your baby is allergic to these nuts without trying.  You will want to be confident and know that it’s safe to feed your baby peanut butter.  Babies with other health conditions and allergies to other food items like eggs have a higher risk of peanut allergy.  You must know if your baby tolerates peanuts or not. I suggest starting it in a safe and controlled environment like your doctor’s or allergist’s office. And the best way to find out is by slowly introducing it to them.  If you know your baby doesn’t have any allergies, you can give them peanut butter at about 4 to 6 months old. It’s not recommended to feed peanut butter as it is because your baby may choke on it. Instead, smoothen the peanut butter by adding water, if necessary, before feeding.  While peanuts can lead to choking, PB is also risky for babies as it is very sticky. So I advise you not just to feed your baby peanut butter. Keep monitoring them the first few times you feed them PB to see if they can swallow it without any problems. There is a chance of them developing symptoms like red eyes, runny nose, and signs of swelling and irritation. While it is normal for babies to have runny noses, keep a watchful eye on your baby for other signs or changes.
