Egg allergy in babies
Egg is a common early allergen and a great first protein. Current guidance leans toward introducing well-cooked egg early, around 6 months, rather than delaying it. Cooking egg thoroughly is important both for food safety and because well-cooked egg is generally introduced first.
Safe ways to serve egg
- Well-cooked scrambled egg, mashed or cut into strips
- Hard-boiled egg, mashed with a little breast milk, formula, or water
- Egg baked into other soft foods

Signs of an allergic reaction
- Hives, redness, or swelling (lips, face, tongue)
- Vomiting or lots of drooling/coughing right after eating
- Widespread rash or worsening eczema
- Trouble breathing, wheezing, or floppiness: call emergency services immediately
General tips for introducing allergens
- Most babies are ready for solids around 6 months, once they can sit with support and show interest.
- Introduce one new allergen at a time and wait about 2 to 3 days before the next, so any reaction is easy to trace.
- Once an allergen is tolerated, keeping it in the diet regularly is part of current guidance.
- Offer allergens earlier in the day (not right before bed) so you can watch for any reaction.
- If your baby has severe eczema or a known food allergy, talk to your pediatrician before introducing peanut or egg.

Frequently asked questions
When can babies eat eggs?
Most babies can try well-cooked egg around 6 months, once they are ready for solids. Introducing egg early is part of current allergen-introduction guidance for most infants.
Can babies have the whole egg or just the yolk?
Both the yolk and white contain nutrients, and the white is where most egg-allergic reactions come from, so offering well-cooked whole egg lets you introduce the allergenic proteins. Ask your pediatrician if your baby is higher-risk.
