Safe Sleep for Newborns: AAP Guidelines Explained Clearly

Room-sharing, back-sleeping, empty cribs, and temperature — the evidence-based safe sleep rules every new parent should know.

Sudden unexpected infant death (SUID), including SIDS, is rare but devastating — and many risks are modifiable. The American Academy of Pediatrics safe sleep recommendations are designed to be simple, consistent, and lifesaving.

The ABCs of safe sleep

Alone: baby sleeps in their own sleep space with no pillows, blankets, bumpers, or soft toys. On their Back: for every sleep, naps included, until age 1. In a Crib or bassinet meeting current safety standards — firm, flat mattress with a fitted sheet only.

Room-share, do not bed-share

Keep baby in the same room as you for at least the first 6 months, ideally a year — but on a separate surface. Adult beds, sofas, and armchairs are high-risk for suffocation and entrapment. If you bring baby into bed for feeding, return them to their bassinet afterward.

Avoid overheating and smoke

Dress baby in one light layer more than you would wear. No hats indoors after the first hours of life unless medically indicated. Keep the room comfortably cool. No smoking during pregnancy or around the baby — exposure significantly raises SIDS risk.

Pacifiers and tummy time

Offering a pacifier at sleep time may reduce SIDS risk after breastfeeding is established. Supervised tummy time while awake builds neck strength — it does not replace back-sleeping for actual sleep.
