How Should Allergens Be Included in a 19–24-Month-Old’s Diet?

Should tolerated allergens stay in the diet?

If a child has eaten a food without a reaction, there is usually no reason to remove it solely because it is a common allergen.

Common allergens include egg, peanut and tree nuts, milk, wheat and other gluten-containing grains, sesame, soy, fish, and shellfish.

A diagnosed allergy is different: avoid the trigger and follow the advice and emergency plan from the child’s healthcare team.

Does an allergen need to be offered every day?

There is no single daily schedule that applies to every allergen or every toddler.

For a food already tolerated, include it as part of the usual varied diet in a form your child can safely eat.

Follow an allergy specialist’s plan if one has been provided; do not change an elimination diet without clinical advice.

Can I offer an allergen the child has never tried?

A food that has not been tried can be offered in an age-appropriate form, one unfamiliar allergen at a time so a possible reaction is easier to identify.

Use a small amount and serve it when your child is well and can be observed. Do not use this approach for a food that previously caused a suspected reaction.

If your child has severe eczema, a known food allergy, or a history of rapid reactions, ask their clinician before introducing another allergen.

How can I serve peanut and tree nuts safely?

Never serve whole nuts to a young child. They can lodge in the airway.

Nut butter can be thinned or spread thinly; avoid a thick spoonful or a dense lump that may be difficult to swallow.

Allergy risk and choking risk are separate: a safe texture does not make a known allergen safe for a child who is allergic.

How can other allergens be included?

Egg, dairy, sesame, wheat, soy, fish, and shellfish can be part of meals when tolerated and prepared safely for the child.

Check fish carefully for bones and cook shellfish thoroughly. Use finely ground seeds or a smooth, thinned seed paste rather than whole seeds where these could be difficult to manage.

Use local food-safety guidance for eggs and other higher-risk foods.

How can I reduce choking risk?

Modify foods for a toddler’s chewing skills: cut, mash, soften, or thin them as needed.

Avoid whole nuts, popcorn, whole grapes, hard chunks, and spoonfuls of thick nut butter. Have your child sit upright and supervise throughout eating.

After introducing a new food, watch your child and note any symptoms and when they began.

What are possible signs of an allergic reaction?

A reaction may include hives or an itchy rash, swelling, vomiting, cough, wheeze, or other symptoms after eating a food.

If you suspect a reaction, stop serving that food and contact a healthcare professional for advice before offering it again.

A single symptom does not establish a diagnosis; a clinician can assess the history and decide whether testing is useful.

When is emergency help needed?

Swelling of the tongue or throat, difficulty breathing or swallowing, collapse, or a rapidly worsening reaction can signal anaphylaxis.

Use the child’s prescribed emergency medicine and action plan if available, and call local emergency services immediately.

Always supervise your child, since allergen safety includes both reaction risk and choking risk.

What can I do today?

Keep foods your child already tolerates in their usual meals, prepared in a safe texture.

Before offering a new allergen, consider the child’s allergy and eczema history and ask a clinician if you are unsure.

Do not test a food at home again after a suspected reaction or remove major food groups without professional guidance.

Check labels and follow the child’s written allergy plan if they have a diagnosed allergy.
