For years, health officials have urged parents to place their sleeping infants on their backs to reduce the risk of sudden infant death syndrome, commonly known as SIDS. But new research suggests many parents aren't listening.
That research says nearly 30 percent of infants are placed face-down on their stomachs. When placed in this position, babies can sometimes not get enough oxygen into their airways and then stop breathing. (ViaFlickr / Lisa Rosario)
