Food allergies are tricky...I would go with the md's advice. My son tested negative to peanut and milk (via blood and skin prick testing)...he was previously allergic to both. Attempted an oral food challenge with milk..failed it cuz he vomited it all up within an hour and a half. He is 2 and they won't even do a oral challenge with peanuts until he is at least 4. If you don't have an epi pen, I would get one just in case. Learn how to use it and have some oral benadryl on hand. Good luck!
