Peanut is one of those foods that worries parents the most. For years the advice was to wait until a child was two or three years old. That advice has changed. We now know that introducing peanut early, in the right form, actually helps protect your baby from peanut allergy. This guide explains when and how to do it safely.
Quick Answer
Babies can be introduced to peanut from around 6 months of age, once they have started other solid foods and are showing signs of readiness (good head control, sitting with support, interest in food).
The key rules:
- Give smooth peanut butter thinned with warm water, milk or mixed into porridge — never thick globs.
- Never give whole peanuts or large lumps — they are a serious choking hazard.
- Early introduction (around 6 months) can lower the risk of peanut allergy, so do not delay it without a medical reason.
- If your baby has severe eczema or an existing egg allergy, speak to your paediatrician first.
Why early peanut introduction is now recommended
The old idea that delaying peanut would prevent allergy turned out to be wrong. A major study called LEAP (Learning Early About Peanut Allergy) found that babies who were given peanut early had a much lower rate of peanut allergy than babies who avoided it.
Because of this evidence, the American Academy of Pediatrics (AAP) and US allergy guidelines (NIAID) recommend introducing peanut early, alongside other solids from around 6 months, rather than waiting. In India, the Indian Academy of Pediatrics (IAP) advises starting complementary foods soon after 6 months, and the same early-introduction approach applies to peanut. Delaying peanut does not protect your baby and may even increase the chance of allergy.
Once peanut has been introduced and tolerated, the next step matters just as much: keep it in your baby’s diet regularly (a small amount a few times a week). Introducing it once and then stopping is not enough.
The choking rule — never whole peanuts or thick globs
This is the part many families get wrong. Early introduction is about the allergen, not the nut itself.
Whole peanuts, and large sticky lumps of peanut butter, are a choking hazard for babies and young children. Whole nuts should not be given until around 4 to 5 years of age.
So how do you serve peanut safely to a baby?
- Thin smooth peanut butter with warm water, breast milk, formula or milk until it is a runny, easy-to-swallow consistency. Stir a small spoonful into porridge, dal, mashed banana or curd.
- Use fine peanut powder or smooth peanut paste mixed into your baby’s usual food.
- Always start with a small taste, not a full spoon of thick butter.
- Sit your baby upright while eating and stay with them.
Never let a baby eat peanut butter straight off a spoon in a thick blob, and never offer crunchy peanut butter or chopped nuts.
High-risk babies — see your doctor first
Some babies are at higher risk of peanut allergy and need extra care. This includes babies with:
- Severe eczema (especially the kind that needs prescription creams and is hard to control), and/or
- An existing egg allergy.
If your baby fits either of these, talk to your paediatrician or an allergist before introducing peanut. Your doctor may recommend an allergy test or supervised introduction in a clinic. This is not a reason to skip peanut — it is a reason to do it under guidance.
How to introduce peanut step by step
- Pick a calm day when your baby is well (no fever, cold or upset tummy) and not too hungry or too tired.
- Offer peanut earlier in the day — morning or midday — so you can watch your baby for several hours, not overnight.
- Introduce it at home, not at a restaurant or while travelling.
- Give peanut on its own as the new food that day — don’t pair it with other brand-new foods, so you know what caused any reaction.
- Start with a small taste of thinned peanut butter or peanut powder mixed into food. Wait a few minutes, watch, then offer a little more.
- If all is well, keep peanut in the diet with small regular servings over the following weeks.
Signs of peanut allergy and what to do
Most babies tolerate peanut with no problem. But watch for reactions, which usually appear within minutes to two hours.
Mild signs:
- A few hives or red, itchy patches on the skin
- Mild swelling around the lips or face
- Some vomiting or an upset tummy
- Runny nose, sneezing or watery eyes
If you see mild signs, stop the food and call your paediatrician for advice before giving peanut again.
Severe signs — this is an emergency:
- Trouble breathing, wheezing or noisy breathing
- Swelling of the lips, tongue or throat
- Repeated vomiting with floppiness or pale, blotchy skin
- A persistent cough, hoarse cry or voice, or trouble swallowing and drooling
- Sudden drowsiness or collapse
If you see any of these, call your local emergency number (dial 112) or rush to the nearest hospital immediately. Severe allergic reactions (anaphylaxis) need urgent medical treatment.
Indian context
In Indian homes peanut (moongphali) is everywhere — in chutneys, sabzis, poha, peanut chikki and ladoos. This makes it easy to add to your baby’s diet, but a few cautions:
- Peanut chikki, gajak and whole roasted peanuts are choking hazards. Keep these away from babies and toddlers; save them for older children.
- Use smooth, additive-free peanut butter or freshly ground peanut paste. Avoid versions with added sugar, salt or chunks.
- Roasted peanut powder (without salt or spice) stirred into khichdi or porridge is an easy, safe way to keep peanut in the diet.
- Be careful with shared snacks at family gatherings, where whole nuts are common.
When to ask your doctor
Speak to your paediatrician if your baby has severe eczema or an egg allergy before starting peanut, if a close family member has a serious nut allergy, if your baby has had any reaction to food before, or if you are simply unsure how to begin. It is always okay to ask.
Frequently Asked Questions
Q: Can I give peanut butter to my 6 month old?
A: Yes, from around 6 months, once your baby has started solids and shows readiness. Use smooth peanut butter thinned with water, milk or porridge into a runny texture — never a thick lump, and never whole peanuts.
Q: How do I introduce peanut safely without choking?
A: Thin smooth peanut butter or use fine peanut powder mixed into your baby’s food. Start with a small taste, keep your baby sitting upright, and stay with them while they eat. Avoid whole nuts and thick globs until around 4 to 5 years.
Q: Does giving peanut early really prevent allergy?
A: Early introduction does not guarantee prevention, but strong evidence from the LEAP study shows it significantly lowers the risk of developing peanut allergy compared with waiting. Keeping peanut in the diet regularly afterwards is important.
Q: My baby has eczema. Can I still give peanut?
A: Mild eczema is usually fine to introduce peanut at home. If the eczema is severe or your baby also has an egg allergy, talk to your paediatrician or allergist first — they may suggest testing or a supervised first taste.
Q: How often should my baby eat peanut after the first taste?
A: Once introduced and tolerated, offer a small amount of peanut a few times a week to maintain tolerance. Stopping after one taste is not enough to keep the protective benefit.
Introducing peanut can feel nerve-wracking, but with the right form and a little watchfulness, most babies do brilliantly. If you would like support from a community of parents going through the same milestones, join our free Babynama WhatsApp community for parents join here.
