Baby Cooked Egg Introduction

Parents safely prepare, offer, observe, or discuss an allergenic food with an infant in a photorealistic home or clinic

Cook egg thoroughly and mash or soften it to the baby's current feeding skill. Do not use raw or lightly cooked egg for first introduction. Seat the baby upright, supervise every bite, and start with a small taste during the day when the baby is well.

Summary

Record the food, preparation, amount, time, and any skin, breathing, stomach, or behavior change. Introduce one new allergen at a time so the history is understandable. If no reaction occurs, gradually use an age-appropriate portion and keep egg in the routine as advised. Do not smear food on the skin as a test or rely on a home test before feeding.

Choose a calm daytime first offer

Begin when the baby is well, early enough in the day to observe, and when help is accessible. Use a small taste first and increase only if no symptom appears and the clinical plan allows. Do not introduce several unknown allergens in one mixed meal, because that makes the history difficult to interpret. Keep the package or ingredient details, write the preparation, amount, and exact time, and avoid smearing food on skin as a test. Skin contact cannot establish safe oral tolerance.

Keep tolerated foods in the routine

Once an allergenic food is eaten without reaction, keep offering it in a developmentally safe form and age-appropriate portion as advised. Keep variety in the diet and continue usual milk feeds. If a reaction later occurs, stop that food and contact a clinician before offering it again.

Recognize possible allergic reactions

Watch for hives, widespread redness, facial or eyelid swelling, repeated vomiting, diarrhea, persistent cough, wheeze, voice or cry change, sudden sleepiness, pallor, or unusual behavior after eating. Stop the food and contact a clinician promptly. A little redness only where acidic food touched the skin can be irritation, but do not diagnose from appearance alone. Record exact onset, food, amount, preparation, all body systems affected, duration, and treatment. Photographs can support a history but must not delay care.

Act on anaphylaxis immediately

Severe breathing or swallowing difficulty, sudden swelling of the lips, mouth, tongue, or throat, blue or gray color, collapse, difficulty waking, or symptoms involving more than one body system can signal anaphylaxis. Use prescribed epinephrine immediately according to the baby's written action plan and call emergency services. Do not wait for a rash, give food or drink, or delay for antihistamine, photographs, a second opinion online, or transport by yourself when emergency services are indicated.
