The American Academy of Pediatrics recommends that all breastfed infants and those who are drinking less than one liter of formula per day get 400 IU of vitamin D3 daily. To make sure your baby is receiving enough vitamin D, a daily supplement may be a great option. Ditamin BabyVit D3 provides 400 IU (10 mcg) of vitamin D3 in a single, convenient, unflavoured drop. Place a drop in your baby’s bottle, or use it while breastfeeding.
