Newborn sleep and safe sleep

What it is

Safe sleep is the set of habits that lower the risk of SIDS and other sleep deaths. You will hear it as the ABCs: Alone, on the Back, in a Crib or bassinet. The American Academy of Pediatrics (AAP) wrote the current rules in 2022.

SIDS is sudden infant death syndrome, a death in sleep with no clear cause. About 3,500 babies in the United States die in their sleep each year. That number includes SIDS, suffocation, and getting trapped in bedding. Most of those deaths are tied to the sleep setup, and the setup is the part you can change.

Newborn sleep itself is messy. A newborn sleeps 14 to 17 hours in every 24, but in pieces of two to four hours. There is no schedule yet. That is normal, not a problem to solve.

What's typical

The risk of SIDS is highest between one and four months. About 9 in 10 cases happen before six months. Room-sharing, with the baby on a separate surface next to your bed, cuts the risk by as much as half. The AAP suggests room-sharing for at least the first six months.

A safe setup looks plain: a firm, flat mattress with a fitted sheet and nothing else. No pillows, bumpers, blankets, or stuffed animals. No inclined sleepers, swings, or car seats for sleep. A pacifier at sleep time is linked to lower risk. Dress the baby in one more layer than you wear, with no hat indoors.

What's known

The AAP says not to share a bed with your baby. It says bedsharing is most dangerous under four months, on a couch, or when an adult has had alcohol or is very tired. La Leche League takes a different view. Its Safe Sleep Seven describes when bedsharing carries lower risk: a nonsmoking, sober, breastfeeding mother, a healthy full-term baby on his back, lightly dressed, on a firm bed with no gaps. The two groups agree on this much: a couch or armchair is never safe, and planning ahead is safer than falling asleep by accident.

What helps

• Set up the bassinet before the birth, within arm's reach of your side of the bed.
• If you are about to doze while feeding, feed in bed with pillows and blankets pushed away, not on the couch.
• Swaddle or use a sleep sack instead of loose blankets. Stop swaddling at the first sign of rolling.
• Keep the room cool. A sweaty neck or flushed face means too many layers.
• Split the night with a partner or helper so one adult is actually rested.
