Most children with egg allergy will outgrow it, some more quickly than others.
At first, children outgrow their allergy to baked egg as an ingredient, in cake for example, while they will still react to lightly cooked egg, such as in pancakes. Over the following months or years, they will begin to tolerate lightly cooked egg, and finally uncooked egg, such as in mayonnaise.
Your allergy specialist can guide you on the best time to re-introduce each type of egg and whether or not you can do this at home. Specialists often repeat skin or blood tests to see when the allergy is improving.
If your child can tolerate baked egg, it’s good to include it in their diets as most specialists now agree that this can speed up how quickly children outgrow their allergy altogether. Always check with your allergy specialist about what forms of egg are okay first.
