Washingtonpost.com: Kids from newborns to teenagers should take twice as much Vitamin D as previously recommended because it may help prevent serious disease, a leading medical group said yesterday.
The new recommendation came from the American Academy of Pediatrics. A pediatrician is a doctor who takes care of kids.
On a side note, was it really necessary for the author to define "pediatrician" for us? Perhaps so, but I find that sad.
