Consider these guidelines from the American Academy of Pediatrics for vitamin D for babies:

Breastfed or partially breastfed babies need 400 international units (IU) of liquid vitamin D a day — starting soon after birth. Babies should continue to receive this amount of vi-ta-min D until weaned or until they drink 32 ounces (about 1 liter) a day of vitamin D-fortified formula or, after age 12 months, whole milk. Babies getting less than 32 ounces (about 1 liter) a day of vi-ta-min D-fortified formula need 400 IU of liquid vi-ta-min D a day — starting in the first few days after birth. Babies should continue receiving the vi-ta-min D supplement until they drink at least 32 ounces (about 1 liter) of vi-ta-min D-fortified formula a day.

When giving your baby liquid vitamin D, make sure not to give more than the recommended amount. Read the instructions that come with the supplement & use only the dropper that"s provided.

While breast milk is the best source of nutrients for babies, it likely won"t provide enough vitamin D. Babies need vitamin D to absorb calcium & phosphorus.

Too little vitamin D can cause rickets, a softening & weakening of bones. Since sun exposure — an important source of vitamin D — isn"t recommended for babies, supplements are the best way to lớn prevent vi-ta-min D deficiency.

As your baby gets older & you địa chỉ cửa hàng solid foods to lớn your baby"s diet, you can help meet the daily vitamin D requirement by providing foods that contain vitamin D — such as salmon, egg yolks and fortified foods.

If you have questions about your baby"s need for vitamin D supplements, talk to your baby"s health care provider.
