When can babies have peanut butter?
From 6 months (corrected age), in the age-right form below.
- Protein and healthy fats that support rapid infant growth
- A natural source of vitamin E and niacin
How do I serve it at each age?
Safe form at 6–8 months
One teaspoon of smooth, salt-free peanut butter thinned with 2–3 teaspoons of warm water, breast milk, or formula to a drizzly, runny-yogurt consistency, stirred into a puree the baby already knows.
Pass/fail test: Lift the spoon: the mixture should ribbon off like runny yogurt. If it clings in a sticky lump, keep thinning.
Why this form: Young infants cannot clear sticky boluses from the roof of the mouth or throat; fully thinned peanut butter delivers the allergen protein with none of the plug-shaped risk.
How to prepare
- Choose 100% smooth peanut butter with no added salt, sugar, or honey (honey is off-limits before 12 months).
- Stir 1 teaspoon with 2–3 teaspoons of warm water, breast milk, or formula until it drizzles off the spoon.
- Mix into a familiar food (oatmeal, fruit puree) — never a brand-new food, so a reaction can be traced.
- First time: serve early in the day, start with a small taste, and watch for 2 hours.
Common mistakes
- Serving a thick glob straight off the spoon — the single most dangerous peanut mistake.
- Using crunchy peanut butter: the nut fragments are a choking hazard.
- Introducing at dinner, where a delayed reaction lands overnight when you can't observe.
- Mixing into another new food, which makes a reaction impossible to attribute.
How much?
One teaspoon, fully thinned, stirred into a familiar puree.
About twice a week once tolerated — steady exposure is what maintains tolerance.
Amounts are starting points, not targets — watch the baby, not the numbers.
How do I get the texture right?
- Thinning ratio to memorize: 1 teaspoon smooth peanut butter to 2–3 teaspoons warm liquid gives the safe drizzly consistency.
- Peanut powder (defatted peanut flour) stirred into a familiar puree is the easiest, safest first form — same allergen protein, zero stickiness.
- After successful introduction, keep peanut in the diet about twice a week (roughly 2 teaspoons of peanut butter per serving) — consistent ongoing exposure is what maintains tolerance.
- Always serve new allergens early in the day so you can observe for the following 2 hours.
Is peanut butter a choking hazard?
High choking risk — prep matters
A thick glob of peanut butter can plug an airway like a stopper, and whole peanuts are off-limits until at least age 4. Mitigate by always thinning smooth peanut butter to a drizzle or spreading it paper-thin — never serve it by the spoonful.
Is peanut butter a common allergen?
Common allergen: Peanut
Yes — introduce it early in the day, alongside familiar foods, and watch for 2 hours. See the Peanut introduction program →
Anything to watch for?
Many jars carry added salt and sugar — the ingredient list should read peanuts and nothing else.
