> Not for routine sleep. The AAP, NIH, and CPSC say swings, bouncers, rockers, and car seats outside the car aren't safe sleep spaces. If your baby dozes off in one, move them onto their back on a firm, flat surface as soon as you can. In the car, a buckled car seat is right.

**Short answer:** Not for routine sleep. The AAP, the NIH's Safe to Sleep campaign, and the US Consumer Product Safety Commission (CPSC) all say swings, bouncers, rockers, car seats used outside the car, strollers, and carriers aren't safe places for a baby to sleep. Babies doze off in them all the time, and that's normal. When it happens, move your baby onto their back on a firm, flat surface, like a crib or bassinet, as soon as you can. A car seat buckled in the car while you travel is exactly where your baby should be.

Adam fell asleep in his car seat on the way home from the store, and I sat in the driveway wondering whether to move him. Here's what the AAP says.

Key takeaways

- **Sitting and inclined devices** can let a baby's head slump forward, chin to chest, which can block the airway.

- **Fell asleep in one?** Move your baby to a flat crib, bassinet, or play yard on their back as soon as you can.

- **Car seats are for the car.** Most sleep deaths in car seats happened when the seat wasn't being used as directed.

- **Awake time is fine** in a swing or bouncer, with your baby buckled in and an adult nearby.

## Why can't babies sleep in a swing, car seat, or bouncer?

Because the seated, tilted position can make it harder for a sleeping baby to breathe. Young babies don't yet have the neck strength to hold their head up. In a seat or on a slope, the head can drop forward, chin to chest, and Safe to Sleep warns that this position can block the airway. A sloped surface can also let a baby's body slide down.

That's why the AAP says babies should sleep on a firm, flat, non-inclined surface, and calls any surface tilted more than 10 degrees unsafe for sleep. The AAP's 2022 safe sleep policy says sitting devices such as car seats, strollers, swings, infant carriers, and slings aren't recommended for routine sleep, particularly for babies younger than 4 months.

| Product | Awake use | For sleep? | If your baby falls asleep | 
| Swing | Yes, buckled in and supervised | No | Move to a flat sleep space | 
| Bouncer or rocker | Yes, buckled in and supervised | No | Move to a flat sleep space | 
| Car seat | For travel in the car | Only while traveling, buckled in | Move once you arrive | 
| Stroller | Yes | Not for routine sleep | Move when you get home | 
| Carrier or sling | Yes | Not for routine sleep | Keep the chin off the chest; move when you can | 

## Can my baby sleep in a swing?

Not as a sleep space. The CPSC says inclined products such as rockers, gliders, soothers, and swings should never be used for infant sleep, and babies shouldn't be left in them unsupervised, unbuckled, or with bedding. A swing can still be a lifesaver for a fussy evening. Use it while your baby is awake and you're nearby, and when their eyes close, move them to their crib.

In 2022, the CPSC and Fisher-Price warned that at least 13 babies had died in the company's infant-to-toddler and newborn-to-toddler rockers between 2009 and 2021, and said rockers should never be used for sleep.

Swings are for awake, supervised time only, never for sleep.

## Can my baby sleep in a car seat?

Yes while you're driving, but not as a place to nap at home. Babies fall asleep in the car constantly, and a correctly buckled car seat is the safest way for them to travel. The risk comes when the car seat becomes a bed: carried inside, set down, and left with a sleeping baby.

A 2019 study in Pediatrics looked at 11,779 sleep-related infant deaths in the US. About 3% (348) happened in sitting devices, and 63% of those were in car seats. In fewer than 1 in 10 of the car-seat deaths was the seat being used as directed, and about half happened at the child's own home. The authors concluded that using car seats for sleep outside of travel may put babies at risk.

On long trips, Safe to Sleep passes on AAP tips such as giving your baby breaks from the car seat every few hours. When you arrive, unbuckle your baby and move them to a flat sleep space.

In the 2019 study, deaths in sitting devices were more likely when a child care provider or babysitter was in charge than when a parent was. Share the "flat and on the back" rule with everyone who looks after your baby.

## What should I do if my baby falls asleep in one?

Move them to a safe sleep space as soon as you can, even if it wakes them. The AAP, Safe to Sleep, and the CPSC all give the same advice.

- Unbuckle your baby and lift them out, supporting their head.

- Lay them on their back in a crib, bassinet, or play yard with a firm, flat mattress and a fitted sheet.

- Leave nothing else in the sleep space: no blankets, pillows, or toys.

- If you're out for the day, bring a portable play yard so naps have a flat place to happen.

My baby is 7 months old now and still falls asleep in the car seat on the way home from errands. I carry the seat inside, unbuckle, and lay the baby down in the crib, even when it means a shorter nap. Some days the nap ends right there, and that's OK.

If your baby falls asleep in the car seat, move them to a flat crib, even if it wakes them.

## Does this change as my baby gets older?

The risk is highest in the first few months, but the rules stay the same until the first birthday. The AAP stresses babies under 4 months, who have the least head control. Safe sleep guidance, on the back, alone, on a flat surface, applies to every nap and night until age 1. The same is true for what goes in the crib; see [when a baby can sleep with a blanket](/when-can-baby-sleep-with-blanket/).

For every sleep until age 1: on the back, alone, in a crib, bassinet, or play yard with a firm, flat mattress and a fitted sheet. No inclined sleepers, wedges, or positioners; inclined sleepers and crib bumpers are now banned in the US. Never sleep with your baby on a sofa or armchair.

**What the research says:** "flat and on the back" is official guidance from the AAP, the NIH, and the CPSC, built on national death-review data and product incident reports. These are observational data, since no one could ethically run a trial, and deaths in sitting devices are rare. But the fix is simple, and the experts are united on it.

If your baby has reflux, breathing problems, or another condition and you've been told to keep them upright to sleep, ask your pediatrician exactly how to do it safely. The AAP's back-to-sleep advice includes healthy babies with reflux.

## Frequently asked questions

**Q: Is it OK if my baby naps in the stroller on a walk?**

Dozing off on a walk with you right there is common. Keep an eye on your baby, check that their chin isn't slumped onto their chest, and move them to their crib when you get home.

**Q: What about falling asleep in a carrier or sling?**

Carriers and slings aren't meant for routine sleep either. If your baby falls asleep while you're wearing them, make sure you can see their face and their chin is off their chest, and lay them down on their back when you can.

**Q: My baby only sleeps in the swing. What can I do?**

Start by moving your baby to the crib once they're asleep, then gradually practice putting them down drowsy but awake. It may take some patient nights. Our guide on [whether sleep training works](/does-sleep-training-work/) covers gentle and faster options from about 6 months.

**Q: Is a play yard safe for sleep?**

Yes. A play yard that meets current US safety standards, used with only its own firm mattress and a fitted sheet, is a safe sleep space, and it travels well.
