How to serve whole nuts by age

6 months+

Finely ground nuts or thinned nut butter

Never give whole or chopped nuts to a baby. Grind plain, unsalted nuts to a fine powder and stir a little into porridge or a purée. Or thin smooth nut butter with water, breast milk or formula until runny. Introduce one type of nut at a time. Toast strips are fine once wheat has been introduced on its own. Our peanut butter and almond butter pages show each step.

Size: Stirred into a smooth food, or spread very thinly on soft toast strips about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
Check before serving: Rub a pinch of ground nut between your fingers: it should feel soft and fine, with no gritty bits. Thinned nut butter should drip easily off a spoon.

US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.

Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.

How to prepare whole nuts

1
Choose plain, unsalted nuts, or smooth nut butter with no added salt or sugar. Never chunky.
2
Blitz the nuts in a clean, dry blender or spice grinder in short bursts until they're a fine powder. Sieve out any bits that won't grind.
3
Stir about ½ teaspoon into a food your baby already eats, such as porridge or puréed fruit. Introduce one type of nut at a time.
4
First time? Pick a day your baby is well, at home, when you can watch them for a couple of hours afterward.

How much to offer

For the very first taste, offer a small amount: about ½ teaspoon of ground nuts stirred into food. If there's no reaction, offer more next time. Your baby decides how much to eat. After that, the goal is to keep each nut your baby tolerates in their diet regularly, not to finish a portion.

Common mistakes

Offering whole or chopped nuts

The CDC lists whole or chopped nuts as a choking hazard for young children. The NHS says no whole nuts under 5. Grind them finely, or blend them completely smooth, until at least 4 years (5 in the UK).

Spoonfuls of thick nut butter

Chunks and spoonfuls of nut butter are a choking hazard. Thin it until runny, or spread a very thin layer on toast.

Leaving nuts within reach

Bowls of nuts and trail mix are easy for toddlers to grab, and the AAP notes older children often share risky foods. Keep them up high and watch at snack time.

Putting nuts off out of fear of allergy

Waiting doesn't prevent allergy, and the NHS says delaying peanut beyond 6 to 12 months may increase the risk. Introduce ground nuts or thinned nut butter from around 6 months, and keep offering them.

Where US and UK guidance differ on whole nuts

United States(AAP and CDC)Your setting

The AAP advises keeping nuts from children until 4 years or older, depending on the child, and the CDC lists whole or chopped nuts as a choking hazard. Finely ground nuts, or smooth nut butter thinned or spread thinly, are fine from around 6 months. For babies with severe eczema or egg allergy, the AAP recommends peanut allergy testing: ask your pediatrician how and when to start.

United Kingdom(NHS)Your setting

The NHS says no whole nuts for children under 5. For babies, its food allergies page says to serve nuts finely ground or as nut butter, spread on a food such as toast and never on its own. Some NHS pages also mention crushed nuts in food; we show only finely ground nuts, the most cautious form. Talk to your GP or health visitor before introducing any nut if your baby has eczema or a diagnosed food allergy, or there's a family history of food allergies, eczema, asthma or hay fever.

We cover US and UK guidance in detail. Elsewhere, check your national health service's advice too.

Questions parents ask

Can whole nuts be a choking hazard for babies?

Whole and chopped nuts are a choking hazard for young children: they're small, hard and difficult to chew. The AAP advises keeping nuts from children until 4 years or older, depending on the child, and the NHS says no whole nuts for children under 5. Until then, serve nuts finely ground, blended completely smooth, or as smooth nut butter thinned or spread very thinly. Never give spoonfuls of thick nut butter.

Can babies be allergic to whole nuts?

Tree nuts, such as almonds, cashews, walnuts and hazelnuts, are one of the most common food allergens, and peanuts (a legume, not a tree nut) are another. Current guidance is to introduce them from around 6 months in a safe form, one type at a time, and keep offering them regularly once your baby tolerates them. Tree nut allergy usually lasts for life: fewer than 1 in 10 people outgrow it. Between 25% and 40% of people with a peanut allergy also react to at least one tree nut.

Are whole nuts healthy for babies?

A source of fat, protein, fiber, magnesium and vitamin E. 100 g of unsalted dry-roasted mixed nuts (with peanuts) has about 227 mg of magnesium and 6 mg of vitamin E.

When can my child eat whole nuts?

Not until at least 4 years in the US (the AAP says 4 or older, depending on the child) and 5 years in the UK. Until then, keep nuts finely ground or blended smooth. When you do start, have your child sit down to eat, and stay with them.

Can babies eat chopped or crushed nuts?

Not chopped: the CDC lists whole or chopped nuts as a choking hazard. NHS guidance allows crushed nuts in food, but we show only finely ground nuts, with no hard bits, for babies and toddlers.

Do I need to introduce each nut separately?

Yes. Each tree nut is a different food, and some people are allergic to one but not others. The NHS advises introducing foods that can trigger allergies one at a time, so you can spot any reaction.

My baby is allergic to peanuts. Can they have tree nuts?

Ask your allergist first. Peanuts are legumes, not tree nuts, but 25% to 40% of people with a peanut allergy also react to at least one tree nut.

If your baby refuses whole nuts

Many babies need 10 or more tries before they accept a new food. Keep offering finely ground nuts or thinned nut butter alongside foods they already like.
Try another form: stirred into porridge, baked into pancakes, or blended into a smooth sauce.
Eat some yourself at the same meal, in a safe form for your baby. Babies copy what they see.
If your baby keeps refusing nuts and you're relying on them as an early allergen, mention it to your pediatrician.

Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.

Buying and storing whole nuts

Store whole nuts sealed and up high, out of your child's reach: they're a choking hazard.
Grind small batches and keep them in a sealed container. Store nut butter as the label directs.
Porridge or purée with ground nuts stirred in keeps for 3 to 4 days in a covered container in the fridge. Pancakes and muffins made with ground nuts can be frozen for 2 to 3 months; reheat only once, to 165°F (74°C), until steaming hot, then let them cool before serving.
Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).

When to talk to your doctor

Contact your pediatrician, GP or health visitor if:

Your baby has severe eczema, egg allergy or another food allergy, or there's a family history of allergies. Talk to your pediatrician, GP or allergist about how to introduce peanut and tree nuts, not about putting them off.
Your baby has had any reaction to a nut, even a mild one. Stop offering it until you've talked to your pediatrician.
Your child had a choking episode on a nut, even if it came out and they seem fine. The NHS advises getting medical help, because part of it could be left behind.
You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.

Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
