If your baby is a preemie, you can still start Ready, Set, Food! as early as 4 months (normal age or number of days since born, it is not necessary to go by the adjusted age). Introducing peanut and egg in an age-appropriate form, in the first year of life (after age 4 months) is consistent with the 2020 USDA-HHS Dietary Guidelines Advisory Committee Report. If you have any questions, we suggest you contact your pediatrician.
