Introducing Eggs to Your Baby: A Parent's Guide

Eggs are one of the top food allergens for babies. But here is something we learned that made us feel less anxious: how you cook the egg can make a difference. Our paediatrician mentioned that some babies tolerate egg baked into muffins or cakes better than scrambled or soft-boiled egg. We are not scientists. We are just parents who found this helpful to know. And it shaped how we approached our egg introduction plan. Run everything by your own doctor before you start.

Direct Answer: Start egg introduction with well-cooked hard-boiled yolk (less likely to trigger a reaction than raw or lightly cooked white), then follow a 14-day plan — pea-sized amount day 1, half a teaspoon day 3, full teaspoon with cooked white day 7, regular meal component day 14 — without introducing other new foods in that window.

Tracking meals and symptoms manually is harder than it sounds. Our app makes it quick, and stays completely private.

Starting with hard-boiled yolk

We started with hard-boiled egg yolk mashed into a purée our baby already ate without issues. The reasoning (from our paediatrician, not us): the yolk is less likely to trigger a reaction than the white, and heating changes the structure of some egg proteins. Some children who react to raw or lightly cooked egg can tolerate egg that has been thoroughly heated, such as egg baked into muffins or cakes (Caubet and Wang, 2011; Lemon-Mulé, 2008). We began with a pea-sized amount, about 1–2 g, and waited 15–20 minutes before offering more. If your baby tolerates yolk, the next step is adding well-cooked white. Some families introduce both from the start. Ask your doctor which approach fits your situation.

Our 14-day egg introduction plan

Same rhythm we used for peanuts: Day 1: pea-sized amount of hard-boiled yolk. Day 3: half a teaspoon of yolk. Day 7: full teaspoon with a small amount of well-cooked white. Day 14: egg as a regular meal component. We kept other new foods out of the rotation during those two weeks. Each day, we jotted down what was eaten, when, and any observations. Nothing dramatic happened. But having the log gave us confidence that if something had, we would have caught it.

Keeping your partner or nanny on the same page

This got tricky when our baby was being fed by three different people across the day. Did Grandma give egg this morning? Is the nanny aware we are in the observation window? Without a shared log, someone inevitably offers the wrong food or re-offers something that caused a mild reaction the day before. We set up a shared baby allergen tracker that everyone could see and update. It stopped the 'did anyone feed him egg today?' group chat messages, which honestly was worth it just for that.

Questions parents ask

Should baby have egg yolk or egg white first?

One approach is to start with hard-boiled egg yolk, because our paediatrician explained that the yolk is less likely to trigger a reaction than the white. If your baby tolerates the yolk, the next step is adding well-cooked egg white. Some families introduce both yolk and white from the start. Ask your doctor which egg introduction approach fits your situation.

Does cooking egg make it less likely to cause a reaction in babies?

Cooking can make a difference with egg. Heating changes the structure of some egg proteins, and some children who react to raw or lightly cooked egg can tolerate egg that has been thoroughly heated. Our paediatrician also mentioned that some babies tolerate egg baked into muffins or cakes better than scrambled or soft-boiled egg. Run any egg plan by your own doctor first.

How much egg should I give my baby the first time?

In our 14-day egg plan, the first offer was a pea-sized amount of hard-boiled yolk, about 1 to 2 g, mashed into a purée the baby already ate without issues. We waited 15 to 20 minutes before offering more. Day 3 was half a teaspoon of yolk. This is just one plan, so ask your paediatrician what amount and spacing suits your baby.

How do I stop grandparents or the nanny giving baby egg by mistake?

A shared log that every caregiver can see and update keeps everyone in step during egg introduction. When several people feed a baby across the day, it is easy to offer the wrong food or re-offer something that caused a mild reaction the day before. In the app, Caregiver Sync optionally shares the observation log across devices using your own Google Drive, encrypted before it leaves your device.
