Quick answer
Most babies can be introduced to smooth peanut butter from around 6 months, once they've started solids and tolerated a few first foods.
Whole peanuts and thick, sticky spoonfuls of peanut butter are choking hazards, so the safe way to serve it is thinned down or spread very thinly. It's the peanut protein that matters for allergy prevention, not the texture.
Peanut is one of the most common food allergens, so introduce it carefully at home — and speak to your doctor first if your baby has severe eczema or an existing egg allergy, as these babies are at higher risk.
When babies can eat peanut butter
Most babies can be introduced to smooth peanut butter from around 6 months, once they've started solids and tolerated a few first foods.
Babies at higher risk of peanut allergy (severe eczema and/or egg allergy) may benefit from introduction as early as 4–6 months — but only after discussing it with your doctor or allergist, who may recommend testing first.
Never give whole or chopped peanuts to children under 5 — they're a serious choking hazard. Use smooth peanut butter (no chunks), thinned or thinly spread.
Once introduced and tolerated, keep peanut in your baby's diet regularly (around twice a week) — ongoing exposure helps maintain tolerance.

How to serve peanut butter for babies
First taste: Mix 1–2 teaspoons of smooth peanut butter into your baby's usual food — warm water, breast milk or formula, yoghurt, or a fruit or vegetable purée — until smooth and runny. Offer a small amount on a pre-loaded spoon.
6–9 months (BLW): Spread a thin layer of smooth peanut butter on a strip of toast (never a thick glob). Thinning with a little water makes it less sticky and safer.
Watch and wait: Introduce on a day you can watch your baby for around 2 hours, ideally in the morning. Start small and build up over the following days if there's no reaction.
9–12+ months: Stir into porridge, swirl into yoghurt, blend into smoothies, or use in baby-friendly baked goods. Always smooth, never chunky, and never by the spoonful on its own.
