A new study finds most parents put their babies in unsafe sleeping positions.

FOX's Anna Welles explains:

The American Academy of Pediatrics report is the first to look at video recordings of parental behavior rather than relying on self reported surveys or police reports after an infants death.

Researchers recorded infants ages 1, 3 and 6 months for one night in their homes... They discovered that a vast majority of parents placed their babies at risk by laying them down on their sides or stomachs using soft sleep surfaces, loose bedding and sharing a bed with their babies.

They say fatigue and exhaustion may play a role in parental decision making. The academy recommends placing babies on their backs for sleeping.
