Is It Safe for My Baby to Sleep in a Car Seat, Swing, Bouncer, or Stroller?
Share
Car seats, swings, bouncers, strollers and other sitting or inclined devices should not be used as your baby's routine sleep space.
If your baby falls asleep in a car seat, stroller, swing, infant carrier or sling, the American Academy of Pediatrics recommends moving your baby to a firm, flat, noninclined sleep surface as soon as it is safe and practical.
A car seat has an essential job: protecting your baby while traveling in a vehicle. But once the trip is over, it should not become your baby's crib.
For routine sleep, use a crib, bassinet, portable crib, play yard or other sleep product that meets applicable federal safety standards, and place your baby on the back to begin every sleep.
- Car seats are essential for safe vehicle travel but are not recommended for routine sleep outside of travel.
- Swings and bouncers are not substitutes for cribs or bassinets.
- Sitting devices are particularly concerning for infants younger than 4 months.
- A young baby's head can fall forward in a seated or semi-reclined position and interfere with the airway.
- If your baby falls asleep in a sitting device, transfer the baby to an appropriate firm, flat sleep surface as soon as safe and practical.
- Do not add pillows, head positioners, blankets or aftermarket padding to try to make a car seat or other device more comfortable for sleep.
- Never place a car seat on a bed, couch, table, counter or other elevated surface.
- Safe-sleep recommendations apply to naps as well as nighttime sleep.
My Baby Fell Asleep in the Car Seat. Do I Really Need to Move Them?
This is one of those parenting moments almost everyone recognizes.
Your baby has been awake for hours.
You finally get into the car, drive around for a few minutes and suddenly the baby is sound asleep.
Then you arrive home.
Now comes the dilemma:
Do you really wake a peacefully sleeping baby?
The answer requires an important distinction.
Your baby's car seat is necessary and appropriate while your baby is traveling in the vehicle.
But a car seat is not intended to replace a crib, bassinet or other appropriate infant sleep surface once the travel situation has ended.
If your baby remains asleep after you arrive, the AAP recommends moving your baby to an appropriate firm, flat sleep surface as soon as it is safe and practical.
Why Isn't a Car Seat an Ideal Place for Routine Sleep?
Young infants do not have the head and neck control of older children and adults.
In a seated or semi-reclined position, a baby's head can fall forward.
That position can affect the baby's airway.
The AAP's evidence review notes that infants younger than 4 months may be particularly vulnerable because of poor head control and the possibility of upper-airway obstruction and oxygen desaturation while positioned in sitting devices.
A car seat is designed to protect your baby during transportation. A crib or bassinet is designed for sleep.
Both are important pieces of baby equipment, but they have different jobs.
Once the car ride is over, let the sleep surface do the sleeping.
Does This Mean My Baby Can't Sleep During a Car Ride?
No.
Babies naturally fall asleep while riding in cars.
The recommendation does not mean parents should try to keep a tired baby awake during transportation.
Your baby should remain correctly positioned and properly restrained in the correctly installed car seat while the vehicle is moving.
Do not remove your baby from the car seat while the vehicle is moving simply because the baby has fallen asleep.
When the trip is finished, however, the car seat should not become the baby's routine sleep location.
What Should I Do When We Get Home?
If your baby remains asleep when you arrive home, move the baby from the car seat to an appropriate infant sleep surface as soon as it is safe and practical.
- Bring your baby safely inside.
- Remove the baby from the car seat.
- Place the baby on the back.
- Use a firm, flat, noninclined infant sleep surface.
- Keep the sleep space free of pillows, blankets, toys and other soft objects.
Yes, sometimes the transfer wakes the baby.
That can be frustrating.
But avoiding a difficult transfer is not a reason to turn the car seat into a crib.
Can I Bring the Car Seat Inside and Let My Baby Finish the Nap?
That should not be your routine plan.
Parents sometimes carry the infant seat into the house and leave the sleeping baby in it because the baby looks peaceful.
The concern is that a sitting device remains a sitting device even after it has been removed from the vehicle.
The safer approach is to move the baby to an appropriate infant sleep surface.
Never Put the Car Seat on a Bed, Couch or Table
A car seat that is removed from its base should be placed only where the manufacturer directs.
Do not place an occupied car seat on a bed, couch, mattress, table, countertop or other elevated surface.
Car seats can tip or fall, and soft or elevated surfaces can introduce additional hazards.
Never place a car seat containing your baby on a crib mattress, adult bed, couch, table or other elevated surface.
Follow the car seat manufacturer's instructions for correct use.
Can My Baby Sleep in a Swing?
Swings can be very soothing.
The movement may calm a fussy baby so effectively that sleep follows almost immediately.
But a swing should not become the baby's routine sleep environment.
If your baby falls asleep in a swing, move the baby to an appropriate firm, flat sleep surface as soon as practical.
CPSC guidance also warns that inclined products such as swings, rockers, gliders and soothers should not be used for infant sleep.
Can My Baby Sleep in a Bouncer?
A bouncer is another product designed primarily for an awake baby—not as a substitute for an infant bed.
If your baby falls asleep in the bouncer, transfer the baby to a crib, bassinet, play yard or other appropriate infant sleep surface.
Do not assume that supervising the baby makes the bouncer an appropriate routine sleep location.
CPSC regulations specifically recognize that calling sleep “supervised” does not eliminate the safety requirements that apply when a product is actually marketed or intended for infant sleep.
What About a Stroller?
Babies frequently fall asleep during walks.
As with other sitting devices, a stroller is not recommended as the baby's routine sleep environment.
If your baby falls asleep while you are using the stroller for transportation, follow the manufacturer's instructions and monitor the baby appropriately.
When you are able to transition your baby safely to an appropriate firm, flat infant sleep surface, do so.
Some stroller systems include separate bassinet-style components specifically designed and approved for infant sleep. If you are using such a product, follow the manufacturer's instructions and confirm that the particular component is actually intended for sleep rather than assuming every stroller attachment is.
What About Baby Carriers and Slings?
Soft carriers and slings are extremely useful for carrying babies, but positioning matters.
The AAP advises that an infant's head remain up and above the fabric, the face remain visible, and the nose and mouth remain free of obstruction.
After nursing in a sling, reposition the baby so that the head is up, the face is clear of fabric and the baby's face is not pressed against the adult's body or the sling.
A carrier should not be treated as a substitute for a safe infant sleep surface.
Why Are Babies Under 4 Months at Particular Risk?
Very young babies have limited control of their heads and necks.
When their heads fall forward, they may not have the strength or developmental ability to reposition themselves effectively.
This is one reason the AAP specifically highlights infants younger than 4 months when discussing sitting devices and sleep.
But this does not mean that routine sleep in sitting devices becomes recommended once a baby reaches 4 months.
The recommendation to use an appropriate firm, flat infant sleep surface continues throughout infancy.
What About Inclined Sleep?
A common misconception is that babies sleep better or more safely when the head is elevated.
For routine infant sleep, the recommended surface is firm, flat and noninclined.
The CPSC states that inclined products with a sleep-surface angle greater than 10 degrees that are intended for infant sleep are prohibited under federal law.
Rockers, gliders, soothers and swings should not be repurposed as sleep spaces simply because a baby appears comfortable in them.
But My Baby Has Reflux. Doesn't the Baby Need to Sleep Elevated?
This is an extremely common question.
Parents understandably worry that lying flat may make reflux worse or increase the chance that a baby will choke.
For most infants with gastroesophageal reflux, safe-sleep recommendations remain the same: place the baby on the back on a firm, flat, noninclined sleep surface.
Do not elevate the crib mattress, use a sleep positioner or place the baby in a swing or car seat for routine sleep simply to treat reflux unless your child's medical team has provided individualized instructions for an unusual medical circumstance.
If your baby has significant vomiting, poor weight gain, feeding difficulty, blood in the vomit, breathing problems or other concerning symptoms, discuss them with your pediatrician.
Should I Add a Head Support or Pillow to the Car Seat?
Do not add aftermarket padding, pillows, positioners or head supports unless they are specifically provided or approved for use with that particular car seat by the manufacturer.
Adding unapproved products can change the baby's position and may interfere with how the restraint system functions.
Use the car seat exactly as instructed by its manufacturer.
Can I Loosen the Straps Once My Baby Falls Asleep?
No.
The AAP specifically advises against leaving infants in car seats and similar products with straps unbuckled or partially buckled.
If your baby is in the car seat during travel, use the restraint system correctly according to the manufacturer's instructions.
If the trip is over and you are ready for the baby to continue sleeping, transfer the baby to an appropriate infant sleep surface rather than loosening the harness and leaving the baby in the seat.
What Is a Safe Place for My Baby to Sleep?
For routine infant sleep:
- Use a crib, bassinet, portable crib, play yard or other infant sleep product that meets applicable federal safety standards.
- Place your baby on the back to begin every sleep.
- Use a firm, flat, noninclined mattress or sleep surface.
- Use only a fitted sheet designed for that mattress.
- Keep pillows, blankets, stuffed animals, bumpers and other soft objects out.
The sleep space does not need to look cozy by adult standards.
For an infant, simple is safer.
What If Moving My Baby Always Wakes Them?
This may be the hardest part of the recommendation for parents.
You finally have a sleeping baby, and transferring the baby to the crib causes those eyes to pop open immediately.
That is frustrating—but it does not make the sitting device a safer sleep space.
Try keeping the environment calm during the transfer.
Dim the lights, minimize unnecessary stimulation and place your baby gently on the back in the appropriate sleep space.
Sometimes the baby will stay asleep.
Sometimes the nap is over.
Safe sleep is still more important than preserving a particular nap.
What Should Grandparents and Babysitters Know?
Make sure anyone caring for your baby understands that a sleeping baby should not simply remain in a car seat, swing or bouncer for convenience.
This is particularly important when a caregiver receives the baby asleep in the removable car seat after a drive.
The AAP specifically recommends that child-care providers be instructed to remove a sleeping baby from the car seat after drop-off and place the baby on an appropriate sleep surface.
Safe-sleep instructions should travel with your baby.
Grandparents, babysitters, relatives and child-care providers should know the same sleep rules you follow at home.
When Should I Call My Pediatrician?
Talk with your pediatrician if your baby:
- Seems unable to breathe comfortably when positioned normally
- Frequently appears to choke or struggle during feeds
- Has persistent or forceful vomiting
- Has poor weight gain
- Has significant feeding difficulty
- Has persistent noisy breathing
- Has pauses in breathing
- Seems unusually sleepy or difficult to awaken
- Has a medical condition that makes you uncertain about standard sleep positioning
Your pediatrician can determine whether your baby needs evaluation or individualized medical guidance.
When Is It an Emergency?
Seek emergency medical attention if your baby:
- Has severe difficulty breathing
- Turns blue or gray
- Has a prolonged pause in breathing
- Becomes limp or unresponsive
- Cannot be awakened normally
- Has another symptom that appears immediately life-threatening
If your baby is unresponsive or not breathing normally, call emergency services immediately.
Frequently Asked Questions
Can my baby sleep in the car seat while we're driving?
Babies commonly fall asleep during car travel. Keep your baby correctly restrained in the properly installed car seat while the vehicle is moving. When travel ends, the car seat should not become the baby's routine sleep location.
Should I wake my baby when we get home?
If your baby remains asleep in the car seat, the AAP recommends moving the baby to an appropriate firm, flat sleep surface as soon as it is safe and practical. The transfer may wake your baby, but the car seat should not be used as a substitute for a crib or bassinet.
Can my baby finish a nap in the swing if I am watching?
A swing is not recommended as a routine infant sleep space. If your baby falls asleep there, move the baby to an appropriate firm, flat sleep surface as soon as practical.
Can a baby sleep in a bouncer if supervised?
Supervision does not turn a bouncer into an appropriate routine sleep surface. Transfer a sleeping infant to a crib, bassinet, play yard or other appropriate infant sleep space.
Can my baby sleep in the stroller during a walk?
Babies commonly fall asleep during transportation. Follow the stroller manufacturer's instructions and, when safe and practical, move your baby to an appropriate firm, flat infant sleep surface for continued sleep. A stroller component specifically designed and approved as an infant sleep surface should be used only according to its manufacturer's instructions.
Is an inclined sleeper good for reflux?
Routine infant sleep should occur on a firm, flat, noninclined surface. Do not use an inclined sleeper, swing, positioner or elevated mattress to treat ordinary infant reflux unless your baby's medical team has provided specific individualized instructions.
At what age can my baby safely sleep in a swing?
There is not an infant age at which a swing becomes the recommended routine sleep surface. Use an appropriate infant sleep product for sleep and follow the swing manufacturer's instructions for awake use.
What if my baby sleeps much better in the car seat?
Some babies do appear to sleep well in sitting or moving devices, but sleeping longer does not make the device an appropriate routine sleep surface. If your baby persistently cannot sleep comfortably on a firm, flat surface, discuss the concern with your pediatrician rather than modifying the sleep environment.
Dr. G's Pearl
One of the hardest things to do as a parent is move a baby who has finally fallen asleep.
I understand the temptation to leave the baby exactly where sleep happened.
But the question isn't simply, “Is my baby sleeping?”
The more important question is, “Is my baby sleeping in a place designed for safe infant sleep?”
Use the car seat for the car. Use the stroller for the walk. Use the swing or bouncer as directed while your baby is awake.
And when it's time for sleep, give your baby a firm, flat, separate sleep space.
