Baby Ddrops are easy to use and specifically designed for breastfed babies. The American Academy of Pediatrics recommends 400 IU per day of vitamin D for all infants who are breastfed or partially breastfed. Baby Ddrops can be sucked off any clean surface such as mother's nipple or a clean finger. Each tiny drop can also be dropped directly into liquids or onto foods once the baby is older and begins to eat solid foods.
