Prep warning
Peanut is a common allergen. Introduce it on its own, in a small amount, early in the day, and wait before adding another new allergen. If your baby has severe eczema or a known egg allergy, talk to your pediatrician about how and when to introduce peanut.
Choking notes
Whole and chopped peanuts are a leading choking hazard and should not be given before about age 5. Even peanut butter can be risky as a thick blob, so always thin it down or spread it in a thin layer.
How to serve by age
6-9 months
Whole peanuts and thick peanut butter are choking hazards, so never give them. Instead, thin a little smooth peanut butter with warm water, breast milk, or formula until it is runny enough to lick off a spoon, or stir fine peanut flour into a puree or porridge. Offer it early in the day so you can watch for a reaction.
Smooth peanut butter thinned to a runny consistency, or fine peanut flour. Never whole, chopped, or in a thick blob.
9-12 months
Keep offering peanut in a safe form so the exposure stays regular. Thinned smooth peanut butter mixed into yogurt, oatmeal, or a fruit puree works well. It can be a little thicker now, but still spreadable and never a stiff lump. Whole and chopped peanuts are still off the table.
Thinned smooth peanut butter mixed into soft food. Still no whole or chopped peanuts.
12-18 months
Spread a thin layer of smooth peanut butter on a soft strip of toast, or bake peanut flour into pancakes and other soft foods. Keep peanut butter thin, since a thick layer can be hard to swallow. Whole and chopped peanuts are still not suitable.
Thin layer of peanut butter on a soft carrier, or peanut flour baked in. No whole or chopped peanuts.
2 years and up
Whole peanuts stay a choking hazard until about age 5, so keep serving peanut as smooth butter, finely ground, or baked into soft foods. A thin spread on toast or peanut flour in baking are easy ways to keep it in the diet.
Smooth or ground peanut and peanut butter only. Whole peanuts not before about age 5.
