Eggs are one of the common food allergens that experts now recommend introducing early, usually around 6 months when your baby is ready for solids, rather than delaying. Start with a small amount of well-cooked egg, offer it regularly once tolerated, and know the signs of a reaction.
For years parents were told to hold off on eggs and other allergens. That advice has flipped. Strong evidence now shows that introducing common allergens like egg early, and keeping them in the diet, actually helps reduce the chance of developing a food allergy. That makes eggs a food to welcome onto the tray, not to fear.
This guide covers when and how to introduce eggs, how to serve well-cooked egg safely, sensible portions, how to keep egg in your baby’s routine, and exactly what an allergic reaction can look like. Talk to your pediatrician first if your baby has severe eczema or a known food allergy, since those babies may need a tailored plan.
Key Takeaways
Introduce eggs early, usually around 6 months, once your baby is developmentally ready for solids.
Serve egg fully cooked, such as scrambled or hard-boiled, never raw or runny.
Start with a small taste, then work up to about a third of a well-cooked egg.
Once tolerated, keep egg in the diet regularly, since ongoing exposure helps prevent allergy.
Know reaction signs, and get emergency care for any breathing trouble or swelling.

When to Introduce Eggs
Most babies are ready for solids, including allergens like egg, around 6 months, once they can sit with support, hold their head steady, and show interest in food. Current guidance from major pediatric groups is to introduce common allergenic foods around 4 to 6 months alongside other first foods, not to delay them, because early introduction is linked to fewer food allergies.1
There is no benefit to waiting, and delaying may even raise the risk for some babies. One important exception: if your baby has severe eczema or an already-diagnosed food allergy, they are higher risk, so talk to your pediatrician about the safest way and place to introduce egg and peanut first.2
How to Serve Egg Safely
Egg must be fully cooked for babies, never raw or runny, both to avoid foodborne illness and to serve it in a safe texture. Cook it until both the white and yolk are firm.
Scramble an egg until firm and cut or mash it to a soft, age-appropriate size.
Hard-boil an egg, then mash the yolk with a little breast milk, formula, or water, and offer soft pieces of white.
Stir well-cooked egg into foods your baby already eats, like oatmeal or a familiar puree.
For baby-led weaning, offer strips of firm omelet the baby can grip. See our guide to baby-led weaning.
Avoid whole grapes, and never serve raw or undercooked egg.
Introduce egg on its own the first time, ideally earlier in the day, so if a reaction occurs you can tell what caused it and you are not far from help. Offer only one new allergen at a time, waiting a few days before adding another.
Solids shaking up sleep?
Starting solids can shift appetite and nights. A short, personalized plan can help your baby adjust smoothly.
Start small and build up. A first taste can be just a little well-cooked egg on the spoon or tray. If there is no reaction, gradually increase toward about a third of a well-cooked egg in a sitting over the following days and weeks.
The part parents often miss is that introducing an allergen once is not enough. To get the protective benefit, keep egg in your baby’s diet regularly, for example a few times a week, once it is tolerated. Consistent exposure over time is what the research links to lower allergy risk. Egg is also a nutritious first food, rich in protein, iron, and healthy fats.
Signs of an Allergic Reaction
Most babies tolerate egg with no problem, but because it is a common allergen it is worth knowing what a reaction looks like. Symptoms usually appear within minutes to a couple of hours.
Mild to moderate: hives or a rash, redness or swelling around the mouth, vomiting, or diarrhea.
Severe: trouble breathing, wheezing, swelling of the lips, tongue, or face, repetitive coughing, paleness or floppiness, which is a medical emergency.
Call emergency services immediately for any signs of a severe reaction.
For milder symptoms, stop the food, contact your pediatrician, and get guidance before offering egg again.
Ordinary messiness, a little face redness from drool or acidic foods, or a single spit-up is not the same as an allergic reaction. When in doubt, check with your pediatrician, and never hesitate to seek emergency care for breathing difficulty or swelling.
Your baby has moderate to severe eczema, which raises food-allergy risk.
Your baby already has a diagnosed food allergy, including to another allergen.
A sibling or parent has a significant food allergy and you are anxious about introduction.
Your baby had any reaction to a previous food.
You are unsure whether your baby is developmentally ready for solids.
Higher-risk babies may need to introduce egg and peanut under a pediatrician’s guidance, sometimes with testing first. For most babies, though, early home introduction of well-cooked egg is encouraged.
Frequently Asked Questions
When should I introduce eggs to my baby?
Most experts recommend introducing eggs early, usually around 6 months when your baby is ready for solids, rather than delaying. Early introduction of common allergens like egg is linked to fewer food allergies. If your baby has severe eczema or a known food allergy, talk to your pediatrician first.
How do I serve egg to a baby?
Serve egg fully cooked, never raw or runny. Scramble it until firm and cut or mash it small, or hard-boil it and offer mashed yolk and soft pieces of white. You can also stir cooked egg into foods your baby already eats, or offer strips of firm omelet for baby-led weaning.
How much egg should I give my baby at first?
Start with a small taste of well-cooked egg. If there is no reaction, gradually increase over days and weeks toward about a third of a well-cooked egg in a sitting. Then keep egg in the diet regularly, a few times a week, since ongoing exposure is what helps prevent allergy.
What are the signs of an egg allergy in babies?
Reactions usually appear within minutes to a couple of hours and can include hives or rash, swelling around the mouth, vomiting, or diarrhea. Severe signs include trouble breathing, wheezing, and swelling of the lips, tongue, or face, which is an emergency. Call emergency services for any severe symptoms.
Should I introduce egg and peanut at the same time?
No. Introduce one new allergen at a time and wait a few days before adding another, so you can tell what caused any reaction. Both egg and peanut are worth introducing early, but offer them separately. For higher-risk babies, discuss the order and setting with your pediatrician first.
