Quick answer
Most babies can have smooth, thinned peanut butter from around 6 months, once they have started solids and show readiness signs such as sitting up with support and good head control. For high-risk babies, meaning those with severe eczema or an existing egg allergy, the AAP recommends introducing peanut earlier, at around 4 to 6 months, but only after an evaluation by your pediatrician or allergist, who may recommend testing first.

Most babies can have smooth, thinned peanut butter from around 6 months, once they have started solids and show readiness signs such as sitting up with support and good head control. For high-risk babies, meaning those with severe eczema or an existing egg allergy, the AAP recommends introducing peanut earlier, at around 4 to 6 months, but only after an evaluation by your pediatrician or allergist, who may recommend testing first.
Peanut is a top-9 allergen, so introduce it deliberately: offer the first taste at home, in the morning, on a day you can watch your baby for about 2 hours. Start with a small amount on the tip of a spoon and do not pair it with another new allergen. Once tolerated, keep peanut in the diet regularly, about 2 teaspoons of peanut butter spread across 2 to 3 servings per week, because ongoing exposure is what maintains tolerance.

Safety Tips
- ✓Never serve peanut butter in spoonfuls, thick globs, or straight from the jar; the sticky texture can block a baby's airway. Always thin it with water, breast milk, formula, or yogurt, or spread it in a very thin layer.
- ✓Never give whole or chopped peanuts to babies and toddlers; they remain a serious choking hazard well into childhood.
- ✓Peanut is a top-9 allergen: introduce it at home, in the morning, on its own, and watch your baby for about 2 hours after the first taste.
- ✓If your baby has severe eczema or an egg allergy, talk to your pediatrician or allergist before introducing peanut; these babies are higher risk and may benefit from supervised introduction at 4 to 6 months.
- ✓Choose smooth, unsalted, unsweetened peanut butter with no chunks, and avoid honey-roasted varieties before 12 months.
- ✓Know the signs of a reaction: hives, swelling of the lips or face, vomiting, or wheezing within minutes to 2 hours. Call emergency services for any trouble breathing or sudden floppiness.

How to serve peanut butter for a 6 month old
At 6 months, never offer peanut butter on its own from a spoon; the thick, sticky texture can block a small airway. Instead, stir 1 to 2 teaspoons of smooth, unsalted, unsweetened peanut butter into 1 to 2 tablespoons of warm water, breast milk, or formula until it is completely runny, then offer it on a preloaded spoon. Mixing it into oatmeal or porridge, plain whole-milk yogurt, or a fruit puree like mashed banana works just as well; the final texture should pour or scoop easily, never sticky or thick. Choose smooth peanut butter with no chunks, no added salt or sugar, no xylitol, and no honey before 12 months. Offer the first taste in the morning at home, watch your baby for about 2 hours, and keep them seated upright and supervised throughout.

How do you cut peanut butter for baby led weaning?
For babies around 6 months, peanut butter should be cut into large pieces that are easy to grasp with their hands. As babies develop their chewing skills, the pieces can gradually become smaller.
How to serve peanut butter baby led weaning?
For BLW, cut peanut butter into strips or wedges that babies can hold. The texture should be soft enough to mash easily with gentle pressure.
Can babies choke on peanut butter?
peanut butter can become a choking hazard if served in small round or hard pieces. Cutting it into larger soft pieces appropriate for baby-led weaning helps reduce choking risk.
How should peanut butter be served to a 6 month old?

Is peanut butter safe for baby led weaning?
peanut butter can be included in baby-led weaning when cut into safe shapes and soft textures that babies can hold and gum.
How small should peanut butter be cut for older babies?
From around 9 months, babies typically use a pincer grasp, so peanut butter can be cut into smaller pea-sized pieces. Continue ensuring pieces are soft enough to mash and watch for any choking risk shapes.
Should peanut butter be cooked or raw for babies?
Cook peanut butter until easily mashable when raw textures are too firm for babies to gum. Soft ripe fruits are often offered raw, while firmer foods are typically steamed, roasted, or boiled until tender.
Can peanut butter be served as a finger food at 6 months?
Yes, peanut butter can be a 6-month finger food when cut into long graspable strips and softened to a mashable texture. Always supervise meals and adjust shape as your baby's chewing skills develop.
How to cut peanut butter for a 7 month old?
At 7 months babies still use a palmar (whole-hand) grasp. Cut peanut butter into long strips about 2-3 inches long and finger-width thick, with part sticking out of the fist for chewing. Soft enough to mash between two fingers.
How to cut peanut butter for an 8 month old?
At 8 months babies are refining grasp and may begin pincering. Continue offering peanut butter in 2-inch strips alongside a few small pea-sized pieces to practice the pincer grasp. Cooked until easily mashable.
How to cut peanut butter for a 9 month old?
At 9 months most babies have developed the pincer grasp. Cut peanut butter into pea-sized pieces (about ½ inch / 1.5 cm) for self-feeding practice. Continue avoiding round, hard, or sticky shapes; soft enough to mash with mild pressure.
How to cut peanut butter for a 10 month old?
At 10 months babies eat a wider variety of textures. Offer peanut butter in pea-sized pieces or small bite-sized cubes (½ inch / 1.5 cm). They can manage slightly firmer textures, but pieces should still mash easily.
How to cut peanut butter for a 12 month old?
From 12 months babies eat in pieces about ½ inch (1.5 cm). Round foods (grapes, cherry tomatoes) must still be quartered until age 4 due to choking risk. Soft enough to chew without much molar work.
Can babies eat peanut butter for breakfast?
Yes - peanut butter can be part of a balanced baby breakfast when prepared in baby-safe shapes. Pair with a protein, healthy fat, or whole grain (eggs, yogurt, oats, nut butter on toast) for a complete morning meal.
