When I was a baby, I was put on my stomach to sleep. Was that wrong?
No. Caregivers were following advice based on the evidence available at that time. Since then research has shown that sleeping on the stomach increases the risk for SIDS. This research also shows that sleeping on the back carries the lowest risk of SIDS, and that's why the recommendation of "back is best" or "back to sleep" has been in place since 1996.
