Hello .. I have gone through your complaints. What your doctor said is true and nice that you had followed him. Generally once if the child was diagnosed allergic to a food item , they may be allergic to it for the life time or may take years to be normal for that food item. It is too early as for now to say that your child is not allergic to peanuts. In order to rule out you can plan for allergen test and check your child IgE levels. Emergency medications like adrenaline, steroids and antihistamine has to be in reach. Take care of your child. Thank you. Good day
