How to serve peanut butter to a baby

Cut food for infants and young children into pieces no larger than one-half inch. Cut cylindrical foods (hot dogs, sausage, string cheese) into short thin strips — round pieces can get stuck in the airway. Cut small spherical foods (grapes, cherries, berries, tomatoes) into small pieces. Cook hard vegetables and fruit until they mash easily. Remove seeds, hard pits, skin and bones.

Is peanut butter a choking hazard?

Yes — Peanut butter is one of the foods the AAP and CDC name on their choking-hazard lists. The danger is almost always the shape rather than the food itself, which is why the serving form above is the whole answer. Cut everything to no larger than half an inch, cut cylindrical foods into short thin strips rather than rounds, and quarter anything round.

Allergies and peanut butter

Peanut butter is one of the common allergens (peanut). The current AAP guidance is to introduce it EARLY rather than delay it: newer research found no benefit to waiting, and for peanut, waiting can increase the chance of an allergy. Offer a small amount in an infant-safe form, watch for a reaction, and then keep it in the diet regularly. If your baby has severe or persistent eczema, or has already had an immediate allergic reaction to a food, especially egg, talk to your pediatrician first about how and when to introduce it.

Watch for diarrhea, rash, vomiting or hives after a new food. Call 911 for trouble breathing or swelling of the face, lips or tongue.

Worth knowing

Peanut-containing products are ideally introduced as early as 4 to 6 months — waiting longer can increase the chance of developing an allergy. Once introduced, keep it in the diet routinely. If your baby has severe or persistent eczema, or has had an immediate allergic reaction to any food (especially egg), talk to your pediatrician FIRST about how and when to introduce peanut.
