Nut butters for babies
Nut butters are one of the easiest ways to introduce peanut and tree nuts early, exactly what you want to do. The whole game is texture: thinned and smooth is a great first food, a thick sticky glob is a choking hazard. Here is how to get it right.
Always thin it, never a glob
This is the one rule to remember. Straight from the jar, nut butter is thick and sticky enough to catch in a small throat. Instead:
- Thin it with warm water, breast milk, or formula until it is loose and smooth.
- Stir it into a purée, yogurt, or oatmeal.
- Spread a very thin layer on a strip of toast.
Each nut is its own allergen
Peanut is a legume and its own allergen; the tree nuts (almond, cashew, hazelnut, walnut) are a separate group, and being fine with one does not guarantee the rest. So introduce each new nut butter on its own, watch it, and choose smooth, single-nut butters with no added salt or sugar. See introducing allergens.
No whole nuts before 5
Whole and chopped nuts are a serious choking hazard and should wait until age 5.[1][2] Thinned nut butter and finely ground nuts stirred into food give the same nutrition and allergen exposure without the whole-nut choking hazard. See how to cut food safely.
Start small and watch
Offer a small amount earlier in the day and keep an eye out over the next few hours and days. Know the signs of a reaction: signs of a food allergy.
Nut butters and ground nuts to explore
Thinned or finely ground, one new one at a time. Peanut and each tree nut is its own allergen, so introduce them one at a time and watch. Everything we cover:

This is general information, not medical advice. If your baby has severe eczema or an existing food allergy, talk to your pediatrician or an allergist before introducing nuts. Call 911 (or your local emergency number) right away if any of these show up soon after a food, on their own or together: swelling of the lips, face, eyes, or tongue; swelling or tightness in the throat, or trouble swallowing; vomiting; hives that spread beyond the mouth and face; trouble breathing, noisy breathing, or wheezing; a cough that keeps going; a hoarse voice; skin or lips that turn pale or blue; or a baby who goes floppy or limp, or is suddenly sleepy or hard to wake. If the only sign is a new rash or a few hives around the mouth or face, stop the food, watch your baby closely, and call your pediatrician. If anything else about your baby worries you, call 911.
Frequently asked questions
Can babies have nut butter?
Yes, thinned and smooth, from around 6 months. Peanut and tree-nut butters are a safe, easy way to introduce those allergens early, which is exactly what current guidance recommends. The catch is texture: a thick, sticky glob of nut butter is a choking hazard, so it always needs thinning or spreading thin.
How do I serve nut butter safely?
Never by the spoonful. Thin it with warm water, breast milk, or formula until it is loose, or stir it into a purée, yogurt, or oatmeal, or spread it in a very thin layer on a strip of toast. The goal is smooth and thin, never a sticky lump that can catch in the throat.
Are all nut butters the same for allergies?
No. Peanut is its own allergen (peanuts are legumes), and tree nuts, almond, cashew, hazelnut, walnut, are a separate group. Being fine with one does not guarantee the others, so introduce each new nut butter on its own and watch it. Start with smooth, single-nut butters with no added salt or sugar.
What about whole nuts?
Whole and chopped nuts are a serious choking hazard and should not be given before age 5, the age the NHS and the NIAID peanut guidelines give. Nut butters (thinned) and finely ground nuts stirred into food give all the benefit and the allergen exposure without the risk. Save whole nuts until then.
