If you only read one guide on this site, make it this one. Thousands of U.S. babies die suddenly and unexpectedly during sleep each year (CDC), and safe sleep practices reduce the risk. The rules are simple. The hard part is following them every single time, at 3 a.m., exhausted.

The ABCs: Alone, on the Back, in a Crib

The American Academy of Pediatrics’ 2022 safe sleep recommendations boil down to:

  • Alone: the baby sleeps on their own sleep surface, not in your bed, on a couch, or in an armchair.
  • On the Back: for every sleep, naps and nighttime, until age 1.
  • In a Crib: or bassinet or play yard that meets current safety standards, with a firm, flat, level mattress and a fitted sheet.

The rest of the list

From the AAP, NIH’s Safe to Sleep campaign, and the CPSC:

  • Nothing else in the sleep space. No pillows, blankets, bumpers, stuffed animals, or positioners. Use a wearable blanket instead of a loose one.
  • Room-share without bed-sharing, ideally for at least the first six months.
  • No inclined sleep. Swings, bouncers, loungers, and car seats outside the car aren’t for routine sleep. If the baby falls asleep in one, move them to a flat surface.
  • Don’t overheat. Dress the baby in no more than one extra layer than you’d wear. No hats indoors for sleep.
  • No weighted sleep sacks or swaddles.
  • Breastfeeding, if possible, and a pacifier at sleep time (once breastfeeding is established) are both associated with lower risk.
  • A smoke-free home and car, and no alcohol or drug use by caregivers around infant sleep.
  • Don’t rely on gadgets. The AAP says not to use home cardiorespiratory monitors or consumer devices to reduce SIDS risk.

Where dads slip up

Most dads know “back to sleep.” The risk usually comes from the situations nobody plans:

Falling asleep with the baby on the couch

This is one of the highest-risk situations there is. If you’re feeding or holding the baby and feel yourself getting drowsy, put the baby in the crib first. If you think you might fall asleep, the AAP says an adult bed with pillows and blankets moved away is less dangerous than a sofa or armchair, and you should move the baby to their own sleep space as soon as you wake.

The “just for a nap” car seat

The baby falls asleep in the car seat on the way home. You bring the seat inside and let them nap. It’s very common. Move them to their crib.

Gifts that aren’t safe

Bumpers, nests, loungers, positioners, and weighted sacks still show up as gifts. Padded crib bumpers and inclined sleepers are banned from sale in the U.S. under the Safe Sleep for Babies Act, but older ones circulate. Smile, say thank you, and don’t use them.

Other caregivers

Grandparents raised babies when the advice was different (many put babies on their tummies). Have the conversation kindly and directly before they babysit. Every sleep, every caregiver, every time.

Setting up the sleep space

A play yard or bassinet by your bed is all you need for the first months. Expensive doesn’t mean safer: a basic play yard meets the same federal standard as a premium bassinet.

Frequently asked questions

Can a baby sleep on their side?

No. The AAP recommends placing babies on their back for every sleep, naps and nighttime, until age 1. Once a baby can roll both ways on their own, you don't need to roll them back, but always start them on their back.

Is bed-sharing safe?

The AAP recommends against bed-sharing because it increases the risk of sleep-related infant deaths. It recommends room-sharing instead: the baby in their own crib or bassinet in your room, ideally for at least the first six months.

Can babies sleep in a swing or car seat?

The AAP advises against routine sleep in sitting devices like swings, bouncers, and car seats outside the car. If the baby falls asleep in one, move them to a firm, flat sleep surface as soon as you can.

Are baby monitors that track breathing recommended?

The AAP says not to use home cardiorespiratory monitors or consumer devices as a strategy to reduce the risk of SIDS. A regular baby monitor is fine for convenience; safe sleep practices are what reduce risk.
