How much sleep does a newborn need?
The average newborn sleeps a total of 14 to 18 hours a day, older infants from 13 to 14 hours, says Jodi Mindell, Ph.D., associate director of the Sleep Disorders Center, Children's Hospital in Philadelphia and author of Sleeping Through the Night: How Infants, Toddlers and Their Parents Can Get a Good Night's Sleep, revised edition (HarperCollins).
