When should you introduce high-allergy foods to your baby?
For most families, introducing high-allergy foods to your baby can begin as soon as you begin solid foods. If you have a family history of food allergies or eczema, be sure to discuss introducing high-allergy foods with your pediatrician as a different approach may be necessary.
While previous guidance recommended delaying the introduction of the top allergenic foods, the American Academy of Pediatrics (AAP) updated these guidelines in 2018 to reflect the latest research. In fact, the early introduction of high-allergy foods, such as peanuts, may help to reduce the likelihood of food allergies [].
It is still best practice to introduce one top allergenic food at a time in order to best be able to identify the cause if an adverse reaction occurs.

Wheat
Babies who are allergic to wheat need to avoid foods such as breads, pastas, and crackers as well as certain whole grains such as farro, rye, and barley. A wheat allergy is separate from a gluten allergy or Celiac disease. Toast and soft pasta are two wheat-based foods that are easily introduced to babies.
Shellfish
A shellfish allergy is different from a fish allergy and includes foods such as lobster, crabs, shrimp, and mussels. Some research shows that a shellfish allergy is more common in adults than children []. Shellfish can be difficult to introduce to babies due to their texture. Try serving it in a puree or chopping it into bite-sized pieces once your baby is able to eat finger foods.

Tree nuts

Peanuts

Whole peanuts and peanut pieces are choking hazards for young babies. Instead, serve peanut butter thinly spread on toast or mixed thinly into oatmeal or yogurt.
Soy
