Why safe sleep matters

Sudden unexpected infant death, including SIDS and accidental suffocation, is a leading cause of death for babies under one year in the United States. The good news is that safe sleep habits lower the risk. Since the national Safe to Sleep campaign began in the 1990s, SIDS rates have dropped substantially.

A is for Alone

Your baby should sleep in their own space, with nothing else in it:

The AAP recommends room sharing without bed sharing, ideally for at least the first six months. Put the crib or bassinet in your room, close to your bed.

B is for Back

Place your baby on their back for every sleep, including naps, until their first birthday. Once your baby can roll both ways (back to tummy and tummy to back) on their own, you can let them stay in the position they choose, but always start them on their back.

Back sleeping does not increase choking. Healthy babies naturally swallow or cough up fluids.

C is for Crib

Use a crib, bassinet, portable crib or play yard that meets current federal safety standards, with a firm, flat mattress that fits snugly. The surface should not be inclined. The AAP advises against letting babies sleep in car seats, strollers, swings or infant carriers outside of travel. If your baby falls asleep in one, move them to a flat sleep surface as soon as you can.

Other ways to lower risk

When baby falls asleep while feeding

It happens to everyone. If you're feeding in bed, remove pillows and blankets from around the baby first. If you fall asleep, move your baby to their own sleep space as soon as you wake. Falling asleep with a baby on a couch or armchair is especially risky, so if you're very tired, feed in bed rather than on a sofa.
