It is always a good idea to stay up to date on current recommendations. The AAP, American Academy of Pediatrics, has specific guidelines for safe sleep practices.
Placing babies (through one year old) on their back to sleep is the most current recommendation for safe sleep. Room sharing is considered ideal for the first six months. This means having your baby on a firm sleep surface, i.e. crib or bassinet, laying on its back somewhere in the room with you the parent. Swaddling your baby is just fine! Keep loose items and bedding away from your baby.

Sleeping in a Rock n’ Play Sleeper is not safe and the item has been recalled.
