Can babies have eggs?

The verdict

Yes. Egg is suitable from around 6 months, at the same time as any other first food, and it is one of the foods health services now actively want introduced early rather than held back.

The NHS lists egg in the protein group for babies from around 6 months, alongside meat, fish, beans and pulses, and says these foods matter because they carry iron and zinc as well as protein. Ireland's HSE, the American Academy of Pediatrics and Australia's ASCIA all put egg in the same place: an ordinary early food, not a food to be treated with suspicion.

What differs between countries is not whether a baby can have egg. It is how thoroughly the egg has to be cooked.

How to serve egg to a baby

Egg is one of the easier first foods because a cooked egg is soft, and softness is what removes choking risk. It still needs shaping to a size and form a baby can manage.

A hard-boiled egg can be mashed with a fork, on its own or into vegetable puree, which is the form ASCIA specifically names when it talks about introducing egg for allergy prevention. Scrambled egg, cooked without salt or butter until it holds together, can be broken into soft pieces. An omelette or a firm frittata can be cut into finger-length strips that a baby can hold in a fist with a bit sticking out; the HSE describes finger food as roughly the size of your own finger.

The general NHS rule for firm foods is to think about size, shape and texture, to cut food into narrow batons and avoid round shapes. A whole hard-boiled egg, or a thick round slice of one, is exactly the round, airway-sized shape to avoid. Quarter it lengthways or mash it.

Egg cooked into other food counts. Pancakes, French toast, egg folded through mashed potato and egg in a savoury muffin all introduce the allergen. What does not count for allergy purposes is a trace of egg in a baked product, so if you are deliberately introducing egg, use recognisable egg.

The advice that reversed

For years parents were told to hold back egg and peanut, on the theory that a later first exposure meant a calmer immune system. That advice has been withdrawn, and the current position is close to its opposite.

The NHS states plainly that evidence has shown that delaying the introduction of peanut and hen's eggs beyond 6 to 12 months may increase the risk of developing an allergy to these foods. ASCIA, whose guidance was updated in 2026, says that delayed introduction of egg and peanut has been shown to increase the chance of babies developing an allergy to these foods, and that well cooked whole egg should be included in a baby's diet soon after they start solids. The AAP's allergy team writes that for many years experts thought avoidance was the answer, that newer research found no benefit to delaying, and that once a baby is ready for solids it can actually be helpful to begin offering small amounts of the foods most likely to cause allergy.

Keeping it in the diet

The second half of that advice gets dropped more often than the first. Introduction on its own is not the protective step; regular continued exposure is. ASCIA's instruction is that once introduced and tolerated, common allergy causing foods should be included at least once a week in age appropriate servings. HealthLink BC uses the same logic: once a baby has eaten an allergen without a reaction, keep offering it regularly.

A baby who has egg once at seven months and then not again until they are two has not been protected by that first taste.

Runny yolks: the real disagreement

This is where the countries part company, and it comes down to a British egg-stamping scheme.

The NHS position is that if hens' eggs carry the red lion stamp, or the box shows a red lion with the words British Lion Quality, it is fine for a baby to have them raw or lightly cooked. It names homemade mayonnaise as an example. Eggs without the red lion mark must be cooked until both the white and the yolk are solid, and so must duck, goose and quail eggs. The reasoning is a food safety assurance scheme covering salmonella controls in British flocks, not a property of eggs in general.

Ireland does not accept that carve-out. The HSE's weaning advice says all eggs need to be thoroughly cooked due to the risk of salmonella, with no exemption for any assurance scheme. Australia's Raising Children Network tells parents to avoid raw or runny eggs and foods containing raw eggs, such as homemade mayonnaise, until 12 months. ASCIA's own wording for allergy introduction is well cooked whole egg, such as mashed hard-boiled.

If you are outside the UK, or you are using eggs without a red lion stamp, cook them until the white and yolk are both firm. That satisfies every authority at once.

How much and how often

The AAP's allergy guidance gives a developmentally appropriate portion for allergen maintenance as about one third of a well-cooked egg, in a form like scrambled or hard-boiled. ASCIA suggests starting far smaller when you first introduce it, around a quarter of a teaspoon of mashed hard-boiled egg mixed into food the baby already eats, doubling the amount at later meals if there is no reaction.

Beyond that, egg is simply a protein food. The NHS suggests young children have around one portion of protein from animal sources such as meat, fish and eggs each day, or two from vegetable sources. There is no official cap on how many eggs a baby may have in a week.

Watching for a reaction

Introduce egg on its own, at a meal earlier in the day, not mixed with three other new foods. The NHS advises introducing allergy-triggering foods one at a time so a reaction can be traced.

Reactions usually appear within minutes and almost always within two hours. The NHS lists swollen lips or face, red itchy watery eyes, wheezing and coughing, an itchy rash, worsening eczema, vomiting, tummy pain and diarrhoea. A mild redness or a few contact hives where food touched the skin around the mouth, without anything else, is usually not an allergic reaction; ASCIA says you should offer the food again.

Breathing difficulty, a swollen tongue or throat, or a baby who goes floppy or pale is anaphylaxis. That is an emergency: call 999, 911 or 112.

If your baby has severe or persistent eczema, or has already reacted to a food, speak to your GP, health visitor or paediatrician before introducing egg at home. The AAP treats that group as needing a plan rather than a home trial.

Where guidance differs

Every authority agrees on the age and on not delaying. The split is on cooking, and it is real rather than cosmetic. The UK alone permits raw and lightly cooked egg for babies, and only for eggs inside a specific British assurance scheme. Ireland, Australia and New Zealand require eggs to be cooked through, and the AAP describes egg for allergen introduction in cooked forms only.

The practical resolution is easy. Cooked-solid egg is acceptable everywhere, meets the allergy advice in full, and is the easier texture to serve safely anyway.
