There have been dramatic improvements in reducing baby deaths during sleep since the 1990s, when recommendations were introduced to place babies on their back for sleep. However, since the late 1990s, declines have slowed. Other recommended safe sleep practices today include eliminating hazards, such as keeping blankets, pillows, bumper pads, and soft toys out of the sleep area. Recommendations also include room sharing but not bed sharing. These practices can help lower the risk of sleep-related infant deaths, including sudden infant death syndrome (SIDS), accidental suffocation, and deaths from unknown causes.
