When can babies have peanut butter?
Can babies have peanut butter?
Babies can have peanut butter from about 6 months, as long as it is thinned or spread very thinly and never served by the spoonful. Peanut is one of the Top 9 allergens, and introducing it early and keeping it in the diet can lower the chance of a peanut allergy. Babies with severe eczema or an egg allergy should see a doctor first, who may advise starting even earlier.
How to serve peanut butter by age
Shapes and textures change as your baby’s grasp and chewing grow.

6 months
Stir about a quarter teaspoon of smooth peanut butter into warm water, breast milk or formula until runny, then mix it into smooth oatmeal, yogurt or mashed banana and offer it on a spoon. Never give it by the spoonful or as a thick glob.

7–8 months
Keep stirring thinned smooth peanut butter into thicker oatmeal, yogurt or lumpier mashed banana. You can also spread a barely-there layer on a soft toast strip about the size of an adult finger for your baby to hold.

9–12 months
Keep spreading smooth peanut butter thinly on toast strips, pancakes or soft bread, or swirl it into porridge and purees. Work up to about 2 teaspoons of smooth peanut butter (about 2 g of peanut protein) about three times a week, roughly 6 to 7 g of peanut protein a week in total.

12 months +
Toddlers can have a thin layer on sandwiches, crackers or apple slices cut thin, or a peanut sauce over noodles. Still avoid globs, spoonfuls and whole or chopped peanuts until at least age 4.
Why it’s good
Peanut butter gives babies protein, healthy fats for brain growth, vitamin E, niacin, magnesium and some iron and zinc. It is energy dense, so a little adds useful calories to a small appetite. Choose a brand made from just peanuts, or peanuts and salt, without added sugar or hydrogenated oils.
Safety notes
- Never give peanut butter by the spoonful or in thick globs. Thick nut butter can stick to the roof of the mouth and block the airway.
- Always thin peanut butter with liquid or spread it very thinly so it does not form a sticky lump.
- Whole peanuts and chopped peanuts are a choking hazard until at least 4 years old. Use smooth, not chunky, peanut butter for babies.
- Pick unsalted or low-sodium peanut butter with no added sugar, and skip flavored spreads with chocolate or honey before 12 months.
- Offer the first taste at home, early in the day, when your baby is well, so you can watch for a reaction over the next two hours.
Introduce peanut butter on its own, then keep it in
Peanut is a Top 9 allergen and a leading cause of severe food allergy in children, so introduce peanut butter early in a small amount and watch for hives, vomiting, swelling, coughing or wheezing. Babies with severe eczema or egg allergy should be seen by a pediatrician before the first taste, and once peanut is tolerated, offer it a few times every week.
