Safe Sleep and the ABCs: Reducing SIDS Risk the AAP Way
Alone, on the Back, in a Crib — the AAP's simple ABCs for safer infant sleep, plus what the research really says about room-sharing.
Safe Sleep and the ABCs: Reducing SIDS Risk the AAP Way
Few things rattle new parents like the fear of SIDS. The reassuring part: the American Academy of Pediatrics boils the safest sleep down to three letters — A, B, C. Every baby, every nap, every night: Alone, on the Back, in a Crib.
A is for Alone
Your baby sleeps safest on their own surface with nothing else in it. No pillows, blankets, bumper pads, stuffed animals, or sleep positioners — these soft items are exactly what can cover a small nose and mouth. Keep the space bare. To keep your baby warm, skip the loose blanket and use a wearable sleep sack instead.
B is for Back
Always place your baby down on their back — for naps and at night — until their first birthday. Back-sleeping is the single most effective thing you can do, and it's why SIDS rates dropped dramatically after the "Back to Sleep" campaign. Once your baby can roll both ways on their own, you don't have to flip them back all night, but you should still start them on their back.
C is for Crib
Use a crib, bassinet, or play yard that meets current US safety standards, with a firm, flat mattress and a tightly fitted sheet — nothing else. Inclined sleepers and recalled products are a real hazard; when in doubt about a hand-me-down, check the Consumer Product Safety Commission before you use it.
Share a room, not a bed
The AAP recommends your baby sleep in your room, close to your bed but on their own surface, ideally for at least the first six months. Studies suggest room-sharing can lower the risk of sleep-related death by as much as half. Bed-sharing is a different story — it raises the risk, especially with a newborn, on a couch or armchair, or if anyone has smoked, had alcohol, or taken medication that causes drowsiness. If you might doze off feeding, a bed cleared of pillows and blankets is safer than a sofa.
A few extras that help
- Offer a pacifier at sleep time once breastfeeding is going well.
- Keep the room comfortable, not hot; overheating raises risk.
- Keep your home and car completely smoke-free.
- Give plenty of supervised tummy time while awake to build strength and prevent flat spots.
Safe sleep can feel strict, but it's one of the highest-impact routines you'll ever build. If you're wrestling with a gifted product, a reflux worry, or a baby who only settles upright, that's a perfect thing to raise with your pediatrician before you improvise a workaround.
