I would like to give my 2yo some smooth peanut butter. AFAIK he hasn't got any allergies, but I am worried in case he might have a nut allergy. Is the reaction instantaneous if they are allergic? If they are OK with a bit of peanut butter, do you not need to worry anymore? How/when did you try nut products? (He has eaten smooth choc and hazlenut spread with no problem). TIA.
