I do not recommend any vitamins to any bf kid (or formula fed for that
matter).  In special circumstances one may need:
Additional iron ie premie
Additional vit D ie up north where little sun
AAP recommends fluoride supplements if low fluoride in area water

Older kids dont need vit just make sure they eat a variety of foods.
Vitamins will not replace deficiencies from a bad diet!! it just gives
you expensive pee!!!!!!
