I recently saw a 9 month old child with proven egg allergy; in vivo and in vitro testing for peanut was negative; is it acceptable to introduce peanut butter to the diet if so desired by the parents? Thank you for your guidance.


Thank you for your inquiry.

There is no reason to withhold peanut from this child’s diet.

Thank you again for your inquiry and we hope this response is helpful to you.
