Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Standard of Care
The participants will be provided with three sets of educational materials to learn about early introduction of food allergens.
No interventions assigned to this group
Enhanced Educational Opportunities
The participants will be provided with three sets of educational materials to learn about early introduction of food allergens, as well as 3 in-person monthly teaching sessions (up to 3 months), lasting 30 minutes to enhance the information and allow for questions. This arm will also have one to two in-clinic feedings of any of the top 9 most allergenic foods. The oral feeding portion will add an additional 1 to 2 hours at the one of the 3 visits.
Educational Sessions and Opportunities on Early Introduction and Sustained Ingestion
The participant will attend three in person sessions on the basics of food allergy, food allergy reactions, feeding safety and readiness, fiber, ultra processed foods, diet diversity, and advancing food textures in the infant diet. The educational sessions will last 20 - 30 minutes every month for three months.
In person feeding session
Participants will attend an in-person feeding of a known top 9 food allergen (hen's egg, cow's milk, peanut, tree nuts, soy, wheat, fin fish, shellfish, and sesame) to the infant at least one time, and up to two times. The clinic feeding will last 1 - 2 hours.
