There are new recommendations today on the amount of vitamin D infants and children need.
The American Academy of Pediatrics is doubling their recommended dose of vitamin D to 400 international units a day, beginning in the first days of life. The change comes after several clinical trials showed 400 iu's will prevent the bone softening disease called rickets and treat it.
Most children don't get enough vitamin d in their diets and parents want to be careful exposing newborn skin to sunlight, which is another source of the vitamin.
