Allergen Introduction
Introducing Eggs to Your Baby: A Parent's Guide
Eggs are a common allergen, but preparation method matters. One family's approach to introducing eggs, from hard-boiled yolk to baked goods, with a sample observation plan.

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.

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 thorough boiling changes the structure of the egg proteins. Some children who react to raw or lightly cooked egg can tolerate it when it is well-heated (PETIT study, 2016). 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 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.
Stop group-chatting about what the baby ate
Caregiver Sync optionally shares the observation log across devices using your own Google Drive. Data is encrypted before it leaves your device, so Google cannot read it. Everyone sees the current schedule. No corporate servers involved.
