Feeding your baby
How much vitamin D should my baby get?Vitamin D is important to help avoid a bone-weakening disease called rickets. All babies should receive 400 IU of vitamin D per day, starting in the first few days of life. This includes breastfed babies and babies who drink less than 1L of infant formula per day.
Our skin makes vitamin D when it gets sunlight. But too much sunlight can be harmful, too. In fact, babies 6 months and older and young kids should stay away from direct sunlight and wear sunscreen at all times when out in the sun. However, sunscreen stops the skin from making vitamin D. The best way to get enough vitamin D is by giving your baby liquid multivitamin drops with vitamin D. They can be found in many pharmacies, and you won't need a prescription for it. Just be sure you've filled the dropper to no more than 400 international units (IU).
