According to guidelines, introduction of peanut foods should be considered for all babies, regardless of risk for food allergy.  

For lower-risk babies without severe eczema or egg allergy, parents should introduce infant-safe peanut foods according to family preferences and cultural practices. Baby should be developmentally ready for solid foods, which typically occurs between 4 and 6 months of age, and peanut should not be the first solid food introduced. 

In high-risk babies with severe atopic dermatitis or egg allergy, peanut-containing foods should be introduced between 4 and 6 months of age to reduce the risk of developing peanut allergy. Pediatric providers can consider screening high-risk infants for peanut-specific serum IgE levels prior to recommending peanut food introduction.
