How Often Should Baby Eat Allergens?

The starting point: once your baby has tried and tolerated an allergenic food, keep it in their diet regularly. Food Allergy Canada suggests about 2–3 times a week. Your baby’s healthcare provider can advise on the frequency, amount, and preparation that suit your baby.

How often should I give my baby allergens after introduction?

Think of introduction as the beginning of a routine. The Canadian Paediatric Society recommends regular ingestion, such as a few times a week, once an allergen has been introduced. It also notes that the optimal frequency is not known for every food.

A baby allergen schedule can help you organize that routine, but it is not a universal feeding prescription. Choose a plan with your healthcare provider and use your tracker to remember what was actually eaten.

Do I need to keep giving allergens after introducing them?

Yes, if the food is tolerated. Keep offering it as part of your baby’s usual diet. If there has been a suspected reaction, stop offering that food and get medical advice before trying it again. A completed checklist or a few uneventful feeds cannot prove that a food will always be safe. Read the American Academy of Pediatrics’ guidance.

How often should baby have peanut butter?

After peanut has been introduced and tolerated, include it regularly. Food Allergy Canada’s general guidance of about 2–3 times weekly is a useful discussion point with your clinician; an individual peanut plan may specify different amounts or frequency.

Texture matters. Thin smooth peanut butter into a familiar purée or cereal. Do not offer whole peanuts or thick spoonfuls of peanut butter to a baby. If your baby has severe eczema or a known food allergy, talk to your clinician about introducing peanut. See the AAP’s peanut feeding guidance.

For first-introduction questions, read when to introduce peanut.

How often should baby eat eggs?

Once tolerated, well-cooked egg can be part of the same regular feeding routine. Canadian guidance recommends offering tolerated allergens a few times a week, in age-appropriate portions. Choose a fully cooked texture your baby can manage. See the Canadian Paediatric Society recommendations.

If your baby has an egg allergy or has reacted to egg, get an individualized plan from their clinician. Do not use a general rotation schedule to decide which forms of egg to offer.

How often should I expose my baby to allergens?

For this guidance, “exposure” means eating the food in a developmentally appropriate form. The practical goal is a regular eating routine after the food is tolerated. Ask your clinician about a long gap, a previous reaction, or a change in your baby’s health before deciding how to restart. Read the guidance on ongoing ingestion.

How to keep allergens in your baby’s diet

Build your routine around familiar meals. Once ingredients have each been tolerated, a meal may include more than one of them. Keep the record simple enough to use on a busy day:

  • Plan: add repeat servings of tolerated foods to upcoming meals.
  • Log: record what your baby actually ate, along with the date and any notes.
  • Review: look at days since the last bite before making the next meal plan.
  • Adjust: keep your clinician’s advice in mind as your baby’s needs change.
