Which of the following is NOT a recommended practice for safe infant sleep?

The practice of smoking in the same room is identified as a significant risk factor for safe infant sleep and is not recommended. Research has consistently shown that exposure to secondhand smoke increases the likelihood of sudden infant death syndrome (SIDS) and other sleep-related deaths. Smoking can impair an infant's ability to wake from sleep and can also affect their breathing, making sleeping environments unsafe when smoking is involved.

The other options are all endorsed practices for promoting safe sleep for infants. For instance, placing infants in a supine or back sleeping position significantly decreases the risk of SIDS. Using a crib or a safe sleep space that follows recommended guidelines is crucial to ensure that the infant is in a secure environment. Additionally, having infants sleep alone—meaning in their own sleep space free from adults, siblings, or loose bedding—is encouraged to reduce the risk of suffocation and overheating. These practices collectively contribute to a safer sleep environment for infants.
