How to Introduce High Allergen Foods to Babies

Learning how to introduce high allergen foods to babies can help parents introduce new foods safely while supporting healthy eating habits. Common allergens such as peanut, egg, dairy, wheat, soy, sesame, fish and shellfish can generally be introduced when a baby is ready for solid foods, usually around 6 months. Current guidance does not recommend delaying these foods simply to prevent allergies, although babies with severe eczema or an existing egg allergy may need medical guidance before peanut is introduced.

1. Wait Until Your Baby Is Ready for Solid Foods

Most babies are ready to begin complementary foods at around 6 months. Signs of readiness include good head and neck control, sitting with support, opening the mouth for food and being able to swallow rather than pushing food out.

Breast milk or infant formula should continue to provide important nutrition as solid foods are introduced.

• Look for developmental readiness
• Start solids around 6 months for most babies
• Continue breast milk or infant formula
• Avoid introducing solids before 4 months

2. Start With Small Amounts

When introducing an allergenic food for the first time, begin with a small amount. This makes it easier to observe how your baby responds.

Introduce the food when your baby is well and when you can comfortably monitor them afterward.

• Offer a small taste initially
• Introduce one new allergenic food at a time
• Observe your baby after feeding
• Avoid introducing several unfamiliar foods at once

3. Introduce Peanut in a Baby-Safe Form

Peanut is one of the most important allergens to introduce appropriately. For most babies, peanut-containing foods can be introduced once they are ready for solids.

Never give a baby whole peanuts or thick spoonfuls of peanut butter because they can cause choking. Smooth peanut butter can be thinned with water, breast milk, formula, yogurt or another suitable food until it has an appropriate consistency.

Babies with severe eczema or an egg allergy should be assessed by a healthcare professional before peanut is introduced. For these babies, peanut may be recommended as early as 4 to 6 months under appropriate medical guidance.

• Use smooth peanut butter
• Thin peanut butter before offering it
• Never give whole peanuts
• Avoid thick, sticky spoonfuls of peanut butter

4. Introduce Well-Cooked Egg

Egg can be introduced once your baby is ready for solid foods. Offer it in a soft, well-cooked form that matches your baby’s eating abilities.

Examples include finely mashed hard-boiled egg or soft scrambled egg.

• Cook egg thoroughly
• Start with a small amount
• Use a soft texture
• Watch for signs of a reaction

5. Introduce Dairy Safely

Dairy products such as plain yogurt and suitable cheeses can be introduced during complementary feeding.

However, cow’s milk should not replace breast milk or infant formula as the main drink before 12 months. Dairy foods such as unsweetened yogurt can be offered earlier when they are appropriate for the baby’s diet.

• Choose plain yogurt without added sugar
• Use age-appropriate textures
• Avoid using cow’s milk as the main drink before 12 months
• Continue breast milk or infant formula

6. Introduce Other Common Allergens Gradually

Other common allergens include wheat, soy, sesame, fish and shellfish. These can be introduced in developmentally appropriate forms once your baby is eating solid foods.

Make sure foods are prepared in a way that reduces choking risks.

• Offer well-cooked fish
• Use smooth sesame products such as tahini when appropriate
• Offer wheat in soft baby-friendly foods
• Prepare foods according to your baby’s eating abilities

7. Watch for Signs of an Allergic Reaction

After introducing a new allergenic food, watch your baby for possible symptoms. Reactions may include hives or a rash, swelling, vomiting, diarrhea or other sudden symptoms.

Breathing difficulties, swelling of the tongue or throat, severe coughing, unusual sleepiness or signs of a serious reaction require urgent medical attention.

If you suspect a serious allergic reaction, seek emergency medical care immediately.

8. Keep Tolerated Allergens in the Diet

If your baby eats an allergenic food without a reaction, it is generally useful to continue offering it regularly in an age-appropriate form rather than introducing it once and then avoiding it.

Regular inclusion can help make the food part of the baby’s normal diet.

• Continue foods your baby tolerates
• Use appropriate textures
• Offer reasonable portions
• Maintain variety in the baby’s diet

9. Take Extra Care With Babies at Higher Allergy Risk

Babies with severe eczema or an existing egg allergy have a higher risk of developing peanut allergy. Parents should speak with the baby’s healthcare professional about peanut introduction before offering it.

A healthcare professional may recommend allergy testing or supervised introduction depending on the baby’s circumstances.

• Discuss severe eczema with a healthcare professional
• Mention any existing food allergy
• Ask about peanut introduction
• Follow individualized medical advice

10. Prevent Choking While Introducing Allergens

Allergenic foods must also be prepared safely. A food can be nutritionally appropriate but still dangerous if its texture or shape creates a choking risk.

Avoid whole nuts, large chunks of food, thick globs of nut butter and other foods that are difficult for a baby to chew or swallow.

• Choose soft textures
• Mash or puree foods when appropriate
• Cut suitable foods into safe pieces
• Always supervise your baby while eating

11. Introduce Foods Without Unnecessary Delays

Parents sometimes worry that allergenic foods should be avoided until a baby is older. Current guidance does not support delaying common allergenic foods beyond the period when babies are developmentally ready for complementary foods simply as a way to prevent allergies.

Instead, introduce suitable foods gradually and safely while considering the baby’s individual health needs.

12. Keep a Record of New Foods

Keeping a simple record can help you remember when a particular allergenic food was introduced and how your baby responded.

This can be especially useful if your baby develops symptoms later.

You can record:

• The food introduced
• The date it was offered
• The amount given
• Any symptoms noticed
• Whether the food was tolerated
