That's the number of babies in the United States who die each year as the result of a sleep-related issue, according to a new report from the Centers for Disease Control and Prevention. The causes vary, but child health experts believe many of the deaths would be preventable if more parents adhered to safe-sleep practices. For instance, babies should be placed on their backs to sleep, but the CDC found that 22 percent of moms placed babies on their side or stomach. Soft bedding — blankets, pillows, bumper pads — should be kept out of the sleep area, but 39 percent of moms said they used soft bedding. And it's a good idea to share a room with an infant but not a bed with a baby. Still, 61 percent of moms told the CDC they had slept with their babies.
