Yes! If your baby is ready to start eating solid foods and does not have severe eczema or an allergy to eggs, giving infant-safe peanut-containing foods is safe. If your baby has severe eczema talk with your baby’s doctor before giving peanut foods 

Eating infant-safe peanut foods to help prevent peanut allergy works best when your baby starts peanut foods early. Babies can be ready as early 4 to 6 months of age, after other solid or pureed foods have been introduced. 

SAFETY ALERT: Whole peanuts and peanut butter straight from the jar are choking hazards and not safe. To make peanut butter safe for your baby you must first mix it with breast milk, formula, or water to thin it out.
