Is peanut butter good for babies?
Peanut butter is an excellent source of protein, healthy fats, niacin, and magnesium. Current evidence strongly supports early introduction of peanut protein to significantly reduce the risk of peanut allergy later in life. Always use smooth only, thinned to a runny consistency. Start with a small amount and watch for 2 hours.
