Description of intervention(s) / exposure
Other interventions - Egg Ladder

Other: Egg Ladder - An egg ladder is a form of home-based dietary advancement therapy that aims to facilitate the development of natural tolerance through the gradual introduction of egg containing foods with increasing quantity and allergenicity through different cooking processes. This intervention involves 5 steps over a 12 month period 1.baked egg, 2.well-cooked egg as an ingredient, 3. well cooked whole egg, 4. lightly cooked whole egg and 5.then raw egg.

Summary
Brief summary
The goal of this study is to test the safety and feasibility of a change in management approach for infants with newly diagnosed egg allergy. Infants with newly diagnosed egg allergy will have egg introduced via a gradual and graded home based approach known as an "egg ladder" supervised by a dietitian. The main questions this study aims to answer are how safe and feasible are home-based dietitian-led "egg ladders" as a treatment pathway to achieve tolerance of egg for newly diagnosed infants with egg allergy.
