Is Co-Sleeping Safe? Bed Sharing Risks & Safer Sleep
Share
The safest way to sleep close to your baby is to share the room, not the bed.
The American Academy of Pediatrics recommends room sharing without bed sharing, ideally for at least the first 6 months. Your baby should sleep on a separate, firm, flat infant sleep surface such as a crib, bassinet, portable crib, or play yard.
Sleeping with a baby on the same adult bed, couch, recliner, or other surface can increase the risk of suffocation, entrapment, strangulation, and other sleep-related infant deaths.
You can still keep your baby close for feeding and comforting. Place the baby's sleep space beside your bed and return your baby there when you are ready to sleep.
- Co-sleeping is an ambiguous term. Room sharing and bed sharing are not the same thing.
- Room sharing means baby sleeps in your room on a separate infant sleep surface.
- Bed sharing means baby sleeps on the same surface as another person.
- The AAP recommends room sharing without bed sharing, ideally for at least the first 6 months.
- Couches and armchairs are particularly dangerous places to fall asleep with a baby.
- Bed-sharing risk is especially concerning with very young babies, prematurity or low birth weight, smoking, alcohol, drugs, sedating medications, extreme fatigue, or soft bedding.
- Bring your baby close for feeding and comforting, but return your baby to the separate sleep space before you go back to sleep.
- Safe-sleep recommendations apply to naps as well as nighttime sleep.
Few infant-sleep topics create as much confusion—or emotion—as co-sleeping.
Part of the problem is that parents use the term to describe two very different arrangements.
A baby sleeping in a bassinet beside your bed is not the same as a baby sleeping beside you on the adult mattress.
The first is room sharing. The second is bed sharing.
That distinction matters because room sharing on separate sleep surfaces is recommended, while bed sharing with an infant is not recommended by the American Academy of Pediatrics.
Here's what parents should know—and how to keep your baby close at night while still creating a safer sleep environment.
Is Co-Sleeping Safe With a Baby?
It depends on what you mean by co-sleeping.
Room sharing is recommended. Your baby sleeps in the same room as you but has a separate sleep surface designed for infants.
Bed sharing is not recommended by the AAP. This means the baby and another person sleep on the same adult bed, couch, recliner, or other surface.
Because the term “co-sleeping” can describe both situations, it is more helpful to use the specific terms room sharing and bed sharing.
What Is the Difference Between Room Sharing and Bed Sharing?
Room Sharing
Your baby sleeps in the same room as you but on a separate sleep surface, such as a crib, bassinet, portable crib, or play yard that meets applicable safety standards.
The AAP recommends room sharing without bed sharing, ideally for at least the first 6 months.
Bed Sharing or Surface Sharing
Your baby sleeps on the same surface as another person.
That surface may be an adult bed, couch, sofa, recliner, or chair.
When parents ask me whether co-sleeping is safe, this distinction is the first thing I want to clarify.
Why Isn't Bed Sharing With a Baby Recommended?
An adult bed is designed for adults, not for infant sleep.
It may contain pillows, sheets, blankets, comforters, soft mattress surfaces, gaps, or other conditions that can become hazardous to a baby.
There is also another sleeping person in the environment.
An exhausted adult can move during sleep without realizing where the baby is positioned.
- Suffocation against soft bedding
- The baby's head or face becoming covered by bedding
- Entrapment between the mattress and a wall or bed frame
- Wedging into gaps
- Strangulation
- Accidental covering or compression by another person
- Falling from the adult bed
Why Are Babies Younger Than 4 Months Especially Vulnerable?
Very young infants have limited head control, mobility, and ability to escape from a dangerous position.
The AAP evidence review identifies infants younger than 4 months as a particularly vulnerable group during bed sharing.
Importantly, this increased risk exists even for a healthy, full-term, normal-weight infant whose parents do not smoke and even when the infant is breastfed.
This does not mean bed sharing becomes recommended once a baby reaches 4 months.
AAP safe-sleep recommendations continue throughout infancy.
What About Premature or Low-Birth-Weight Babies?
Infants born prematurely or at low birth weight are particularly vulnerable to sleep-related risks.
These babies may have less mature respiratory control, motor ability, and arousal responses.
If your baby was premature or had a low birth weight, following safe-sleep recommendations is especially important.
Is Sleeping With a Baby on a Couch or Recliner Safe?
No.
This deserves special attention because falling asleep this way can happen very easily.
You sit on the couch for a nighttime feeding. The room is quiet. Your baby is warm against you. You have barely slept.
Then suddenly you wake up and realize you fell asleep.
Couches and armchairs create particularly dangerous situations because a baby can become trapped between an adult and the cushions, wedged against the side of the couch, or have the face obstructed by soft material.
Couches and armchairs are particularly dangerous places to fall asleep with an infant.
If you are becoming sleepy while holding or feeding your baby on a couch or recliner, move to a safer situation before you fall asleep.
What If I Bring My Baby Into Bed to Breastfeed?
Many parents bring their babies into bed for nighttime feeding.
Feeding your baby in bed while you are awake is different from planning for the baby to sleep there.
The safest plan is to return your baby to the separate infant sleep surface when you are ready to sleep.
But sleep deprivation is real, and parents sometimes unintentionally fall asleep while feeding.
If there is a realistic possibility that you may fall asleep while feeding in bed, remove pillows, sheets, blankets, pets, and other soft or loose objects from the immediate area where the baby is being fed.
If you accidentally fall asleep, return your baby to the separate infant sleep surface as soon as you awaken.
Safe-sleep advice has to work at 3 a.m., not just sound good during a daytime doctor's appointment.
If you know you're exhausted, think about the nighttime feeding setup before you're barely able to keep your eyes open.
The goal is to avoid unexpectedly falling asleep with your baby in one of the most dangerous places—especially a couch or armchair.
What Makes Bed Sharing Even More Dangerous?
Certain circumstances substantially increase the risks associated with sharing a sleep surface with an infant.
- The adult is extremely fatigued or difficult to awaken.
- The adult has consumed alcohol.
- The adult has used marijuana, opioids, illicit drugs, or other substances that impair alertness.
- The adult has taken medication that causes significant drowsiness or makes waking more difficult.
- A parent or caregiver currently smokes.
- The pregnant parent smoked during pregnancy.
- The infant is younger than 4 months.
- The infant was born prematurely or at low birth weight.
- The sleep surface is soft.
- Pillows, blankets, or other soft bedding are present.
- The baby shares the surface with someone other than a parent, including another child.
These factors do not represent the entire risk of bed sharing. They make an already nonrecommended sleep arrangement even more hazardous.
Does Breastfeeding Make Bed Sharing Safe?
No.
Breastfeeding is associated with a reduced risk of sleep-related infant death and has many health benefits.
But breastfeeding does not transform an adult bed into an infant-safe sleep surface.
A breastfeeding baby should still be placed on a separate infant sleep surface when the parent is ready to sleep.
Both recommendations can coexist:
Support breastfeeding and practice safe infant sleep.
What About Alcohol, Marijuana, or Sedating Medication?
Anything that reduces an adult's ability to awaken or respond normally makes surface sharing particularly dangerous.
This includes alcohol and other substances that impair alertness.
Some prescription and over-the-counter medications can also cause significant drowsiness.
If you are unsure whether a medication may impair your alertness, ask your physician or pharmacist.
If you have consumed alcohol or used a substance or medication that significantly impairs your alertness, do not sleep on the same surface with your baby.
What About Smoking or Nicotine Exposure?
Exposure to tobacco smoke and nicotine is associated with an increased risk of sleep-related infant death.
Bed sharing is especially hazardous when a caregiver smokes, even if that person does not smoke while actually in bed.
The safest approach is to avoid nicotine and smoke exposure during pregnancy and after birth and keep the infant on a separate safe sleep surface.
Can My Older Child Sleep in Bed With the Baby?
No.
An infant should not share an adult sleep surface with siblings or other children.
A sleeping child cannot reliably monitor a baby's position or respond to a dangerous situation.
Should Twins Sleep Together?
The AAP recommends separate sleep surfaces for twins and higher-order multiples.
Each baby should have an appropriate individual infant sleep space.
Are Bedside Sleepers the Same as Bed Sharing?
No—not when the product provides the baby with a separate sleep surface and meets applicable infant sleep safety standards.
A bedside sleeper can keep your baby close while maintaining a separate infant sleep area.
Always use the product exactly according to the manufacturer's instructions and limitations.
Do not improvise by attaching an ordinary bassinet or crib to an adult bed in a way the manufacturer did not intend.
Can a Product Make Bed Sharing Safe?
Be cautious with products marketed as making bed sharing safe.
The AAP reports that there is insufficient evidence to recommend devices promoted as making bed sharing safe.
A product marketed as a “co-sleeper,” nest, pod, or similar device should not automatically be assumed to make an adult bed safe for infant sleep.
The safer solution is straightforward:
Give your baby a separate sleep surface designed and safety-tested for infant sleep.
What Is the Safest Way to Sleep Close to My Baby?
- Place a crib, bassinet, portable crib, or play yard close to your bed.
- Place your baby on the back to begin every sleep.
- Use a firm, flat, noninclined infant sleep surface.
- Use only the fitted sheet designed for the mattress.
- Keep pillows, blankets, bumpers, stuffed animals, and other soft objects out of the baby's sleep space.
- Bring your baby close for feeding and comforting while you are awake.
- Return your baby to the separate sleep space when you are ready to sleep.
- Follow safe-sleep practices for naps as well as nighttime sleep.
Why Does the AAP Recommend Room Sharing?
Room sharing keeps your baby physically close while preserving a separate infant sleep surface.
The AAP recommends room sharing without bed sharing, ideally for at least the first 6 months.
It also makes practical sense for many families.
Your baby remains close enough for nighttime feeding and comforting without needing to sleep in the adult bed.
What If My Baby Won't Sleep Unless They're Next to Me?
This is where safe sleep can become difficult in real life.
Some babies strongly prefer contact and wake quickly when placed down.
You can feed, cuddle, and comfort your baby while you are awake.
When you are going to sleep, move your baby to the separate infant sleep surface.
If severe exhaustion is making this increasingly difficult, involve your partner or another trusted adult when possible so caregivers can obtain protected periods of sleep.
Persistent sleep difficulty can also be discussed with your pediatrician.
What If I Accidentally Fall Asleep With My Baby?
Accidental sleep can happen to exhausted parents, particularly during nighttime feeding.
As soon as you awaken, place your baby back on the separate safe sleep surface.
Then use what happened to make the next feeding safer.
- Were you feeding on a couch or recliner?
- Were you more exhausted than you realized?
- Could another trusted adult help with part of the nighttime routine?
- Can the bassinet or crib be positioned closer to your bed?
Planning for exhaustion is more useful than pretending exhaustion will not happen.
Frequently Asked Questions About Co-Sleeping
Is co-sleeping safe?
It depends on what you mean by co-sleeping. Room sharing—sleeping in the same room while your baby has a separate infant sleep surface—is recommended. Bed or surface sharing with an infant is not recommended by the AAP.
Is it safe to sleep with my newborn in my bed?
The AAP does not recommend bed sharing with an infant. Babies younger than 4 months are particularly vulnerable to sleep-related risks associated with surface sharing.
Is bed sharing safe if I don't smoke or drink?
Avoiding smoking, alcohol, and sedating substances removes important additional hazards, but it does not make bed sharing the AAP-recommended sleep arrangement. Room sharing on separate sleep surfaces remains the recommendation.
Is sleeping with my baby on my chest safe?
Holding your baby on your chest while you are awake and alert is different from sleeping while holding your baby. If you are becoming sleepy, place your baby on a separate safe infant sleep surface.
Is sleeping with my baby on the couch safer than bed sharing?
No. Couches and armchairs are particularly dangerous places to fall asleep with an infant because of suffocation, entrapment, wedging, and overlay risks.
Can I breastfeed my baby in bed?
Yes. Parents commonly bring babies into bed for feeding while awake. The baby should be returned to a separate infant sleep surface when the parent is ready to sleep. If there is a possibility you may unintentionally fall asleep during feeding, avoid couches and armchairs and remove soft or loose objects from the immediate feeding area.
When does bed sharing become safe?
AAP safe-sleep recommendations apply throughout the first year of life and do not designate an infant age at which bed sharing becomes recommended.
How long should my baby sleep in my room?
The AAP recommends room sharing without bed sharing, ideally for at least the first 6 months.
What is the safest way to co-sleep with a baby?
If by co-sleeping you mean keeping your baby close at night, the recommended arrangement is room sharing without bed sharing. Put your baby's crib, bassinet, portable crib, or play yard close to your bed so your baby is nearby but still has a separate infant sleep surface.
Keep your baby close enough to hear, feed, and comfort—but give your baby a separate place to sleep.
After many years of caring for newborns, I understand why exhausted parents bring their babies into bed. At 2 or 3 in the morning, convenience and exhaustion are very real.
Put the bassinet or crib close to your bed. You can have much of the closeness parents want while preserving the separate sleep surface babies need.
The Bottom Line
Co-sleeping can mean two very different things.
Room sharing—keeping your baby close while your baby sleeps on a separate infant sleep surface—is recommended.
Bed sharing—sleeping with your baby on the same adult bed or other surface—is not recommended by the American Academy of Pediatrics.
The practical goal is not to separate you from your baby.
It is to keep your baby close for feeding, comforting, and nighttime care while giving your baby a separate, firm, flat sleep surface designed for infant sleep.
