How to Introduce Allergenic Foods to Babies Safely

Updated: Sep 29

Introduce allergenic foods to babies during their first year—a big and exciting milestone. While it can feel a little daunting, especially with concerns about food allergies, this guide will walk you through how to introduce allergenic foods to babies safely and confidently.


 

Introduce allergenic foods to babies: Start with Single-Ingredient Foods.


When you’re ready to introduce allergenic foods to your baby, start with one new food at a time. This makes it easier to spot any allergic reactions. For example, if you’re introducing peanuts, shellfish, or eggs, offer them individually without mixing them with other foods. If your baby doesn’t show any signs of an allergic reaction, you can keep including these foods in their diet a couple of times a week. Some doctors suggest offering the same food for a few days, while others believe a single day is enough.

Don’t Delay Introducing Allergens


There’s no need to wait to introduce allergenic foods to babies. Once your baby is ready to start solids—usually between 4 to 6 months old—it’s safe to offer a variety of foods, including common allergens. If a food allergy shows up, it’s better to identify it early so you can manage it effectively with your pediatrician’s help.

Keep Allergens in Your Baby’s Diet


If your baby doesn’t react to an allergenic food, continue to include it in their regular diet. This helps prevent the development of allergies later on. Once you’ve safely introduced each allergenic food individually, you can start mixing them with other foods in your baby’s meals, offering them at least twice a week.

Conclusion:


Introduce allergenic foods to babies while keeping in mind that every child is different, and their reactions to new foods can vary. Monitoring your baby closely during this process is crucial. If you notice any unusual symptoms, be sure to consult with a healthcare professional.
