Vitamin D
Vitamin D helps babies build strong bones and teeth. If babies don’t get enough of this nutrient it can lead to a bone disease called rickets.
Babies who are breastfed or partially breastfed need a vitamin D supplement of 10µg (400 IU) per day. You can get these drops over-the-counter at your local pharmacy. Breastfed babies should start the drops as soon as they are born. When your baby starts getting enough vitamin D from other foods, generally around one year of age, you can stop giving the supplement.
Vitamin D is already added to infant formula.
