The American Academy of Pediatrics (AAP) now says to introduce your infant early and often to allergens.
Those recommendations focus on a high-risk population—infants with severe atopic dermatitis and/or egg allergy—who are advised to introduce infant-safe forms of peanut as early as 4-6 months, in specified amounts, with consideration of pre-testing to rule out allergy. The guidelines recommend that infants with mild to moderate eczema be introduced to infant-safe peanut-containing foods as early as 6 months of age, and those without food allergy or risk factors do so when age appropriate and depending on family preferences, i.e., after 6 months of age if exclusively breastfeeding.
The reason for the change was mounting evidence over the years suggested that delaying introduction of allergens was not preventive.
