Educational SupportEarly Introduction and Sustained Ingestion (EISI) Using Two Educational Opportunities in Infants

The participants in the standard-of-care (SOC) group will be provided with three sets of nonsynchronous educational materials or modules to learn about early introduction of known food allergens and infant nutrition. A quiz will follow each educational module. Participants have the option to come to the research clinic to introduce known allergenic foods under clinician supervision. If none of the 9 most common known allergenic foods in the US (peanut, tree nut, hen's egg, cow's milk, soy, sesame, finned fish, shell fish, wheat) have been fed to the infant by the end of 3 months study enrollment the participant will be required to return to the research clinic for an introductory feeding of a known allergenic food of their choice under clinical supervision. The oral feeding will last approximately 1 hour.

The participants in the experimental group will be provided with the same three sets of educational materials or modules as the SOC group to learn about early introduction of food allergens and infant nutrition. Experimental participants will also attend 3 in-person or live video conferencing education sessions paired with each of the 3 educational modules. The educational classes last 30 minutes and are meant to enhance the information and allow opportunities for questions. The same quiz as the SOC group will follow each educational module. This arm will be required to return to the research clinic for at least one introductory feeding of a known allergenic food (peanut, tree nut, egg, milk, soy, sesame, finned fish, shell fish, wheat) during the first three months of the study under clinician supervision. The oral feeding will last approximately 1 hour.

The participant will receive and review three educational modules on the basics of food allergy, food allergy reactions, food allergen introduction, feeding safety and readiness, fiber, fermented food, ultra processed foods, diet diversity, and advancing food textures in the infant diet. The educational sessions will take approximately one hour to review every month for three months.

Clinician supervised feeding introduction of a known allergenic food (hen's egg, cow's milk, peanut, tree nuts, soy, wheat, fin fish, shellfish, and sesame) to the infant at least one time during the 6 month enrollment. The feeding is required for the intervention group and optional for the standard-of-care (SOC) group. Participants in the SOC group who do not introduce any known allergenic foods at home into the infant's diet by the end of 3 months enrollment will be required to return to the clinic for a clinician supervised feeding of a known allergenic food of their choice. The clinic feeding will last approximately 1 hour.
