Co-sleeping means sleeping close to your baby, and whether it is safe depends on which kind you mean: sharing a room is recommended, while sharing a bed with an infant is not.
Almost every new parent wrestles with this. Your baby settles the moment they are next to you and wakes the moment you put them down. At 3 a.m., bringing them into your bed can feel like the only way anyone will sleep.
This guide explains what co-sleeping means, what the American Academy of Pediatrics recommends and why, when bed sharing is most dangerous, how co-sleeper products compare, what to do if you fall asleep while feeding, and how to move your child to their own sleep space when you are ready.
Key Takeaways
Co-sleeping covers both room sharing (separate surface, same room) and bed sharing (same surface).
The AAP recommends room sharing without bed sharing, ideally for at least the first 6 months.
Risk is highest on sofas and armchairs, with alcohol, drugs, or smoking, with soft bedding, and with babies under 4 months or born early.
If you might fall asleep while feeding, a cleared adult bed is safer than a couch. Move your baby when you wake.
Bedside sleepers that meet federal standards keep your baby close on a separate surface. Padded in-bed sleepers are not recommended.

What Is Co-Sleeping?
Co-sleeping means sleeping close to your baby. The word is used loosely, and that causes a lot of confusion, because it covers two very different arrangements:
Room sharing: your baby sleeps in your room on their own separate surface, such as a crib, bassinet, or play yard placed near your bed.
Bed sharing: your baby sleeps on the same surface as you, usually an adult bed.
When pediatricians warn about co-sleeping, they mean bed sharing. When they recommend keeping your baby close at night, they mean room sharing. You may also see the word “co-sleeper,” which usually refers to a product: a bedside bassinet that attaches to the adult bed, or a small padded bed placed in the adult bed. Those are covered below.
Is Co-Sleeping Safe? What the AAP Says
The American Academy of Pediatrics (AAP) recommends room sharing without bed sharing. In its 2022 safe sleep policy, the AAP advises that babies sleep in the parents’ room, close to the parents’ bed but on a separate surface designed for infants, ideally for at least the first 6 months.
On bed sharing, the AAP’s guidance for parents is direct: avoid bed sharing with your baby under any circumstances, including with twins and other multiples. The reason is the risk of sleep-related infant death, which includes sudden infant death syndrome (SIDS), accidental suffocation, and entrapment. Adult beds have soft mattresses, pillows, blankets, and gaps that were never designed for an infant.
Room sharing, on the other hand, is protective. The AAP notes that keeping your baby’s sleep space in your room can lower the risk of SIDS by as much as 50 percent, and it makes it easier to feed, comfort, and watch your baby.
When Bed Sharing Is Most Dangerous
The risk of bed sharing is not the same in every situation. According to the AAP, the risk of sleep-related infant death rises sharply in these circumstances:
Situation
How much higher the risk is
Sleeping with a baby on a couch, soft armchair, or cushion
Up to 67 times higher
Bed sharing with someone who is impaired by alcohol, marijuana, sedating medications, or other drugs, or who is very fatigued
More than 10 times higher
Bed sharing with a baby younger than 4 months
5 to 10 times higher
Bed sharing with a baby who was born preterm or at a low birth weight
2 to 5 times higher
Bed sharing with someone who smokes, or if the mother smoked during pregnancy
Higher
Bed sharing on a soft surface, or with pillows, blankets, or other soft bedding
Higher
Bed sharing with someone who is not the baby’s parent, including siblings and pets
Higher
Circumstances that raise the risk of bed sharing, according to the American Academy of Pediatrics.
The couch deserves special attention. Many parents move to the sofa or a recliner at 3 a.m. because they are afraid of falling asleep in bed. That is the most dangerous choice of all. A baby can slide into the cushions or become wedged against an adult’s body within moments.
If You Might Fall Asleep While Feeding
Real life with a newborn includes moments when you are so tired that sleep takes over. The AAP addresses this honestly. If there is any chance you might doze off while feeding or comforting your baby:
Feed your baby in your bed instead of on a sofa or cushioned chair.
Before you start, clear away pillows, blankets, sheets, and anything else that could cover your baby’s face, head, or neck.
If you do fall asleep, move your baby to their own sleep space as soon as you wake up.
Two practical habits help as well. Ask your partner or another adult to take the baby, or to check on you, when you are feeding while very drowsy. And if you are worried about nodding off, set a quiet alarm for 15 to 20 minutes before you start.
This is not the same as planning to bed share. It is a way to make an unplanned moment less risky.

Very common. In a Centers for Disease Control and Prevention analysis of national survey data, about 61 percent of mothers reported bed sharing with their baby at least some of the time. If you have done it, you are in a large group of loving, exhausted parents.
You will also find different advice depending on where you look. Some organizations, such as the United Kingdom’s National Health Service and the Lullaby Trust, pair the message that a separate cot is safest with detailed advice on reducing risk for parents who do bed share. The Academy of Breastfeeding Medicine takes a similar risk-reduction approach for breastfeeding families. The AAP reviewed the same research and concluded that it cannot recommend bed sharing in any situation.
What every one of these groups agrees on is the list of situations to always avoid: sofas and armchairs, alcohol or drugs, smoking, soft bedding, and babies who are very young, premature, or small at birth.
Co-Sleepers, Bedside Sleepers, and In-Bed Sleepers
Products sold as a “co-sleeper” fall into two groups, and they are not equally safe.
Bedside sleepers are bassinets that sit against or attach to the side of the adult bed. Your baby has a separate, firm, flat surface with its own walls, but is within arm’s reach. Bedside sleepers have their own federal safety standard (16 CFR part 1222). A model that meets it is one way to room share.
In-bed sleepers are small padded beds, nests, or loungers that sit on top of the adult mattress. Since June 2022, a federal rule has required any product marketed for infant sleep to meet the safety standard for a crib, bassinet, play yard, or bedside sleeper. Most padded in-bed products do not. The AAP advises against using them for sleep, and against loungers and nursing pillows as sleep spaces.
When you shop, look for:
A statement that the product meets the CPSC standard for bassinets and cradles or for bedside sleepers.
A firm, flat sleep surface with no incline greater than 10 degrees.
A secure attachment to your bed with no gap a baby could slip into.
A clear weight limit, and instructions to stop when your baby can roll or push up.
Room sharing gives you most of what parents want from co-sleeping, closeness, easy night feeds, and peace of mind, without a shared surface. To set it up:
Place a crib, bassinet, or play yard within arm’s reach of your bed.
Put your baby down on their back for every sleep.
Use a firm, flat mattress with a fitted sheet only. No pillows, blankets, bumpers, or toys.
Dress your baby in a wearable blanket or sleep sack instead of loose covers.
Keep the room at a comfortable temperature and avoid overheating.
Offer a pacifier at sleep time once feeding is going well.
The AAP’s safe sleep recommendations apply to the first year of life, when the risk of SIDS and accidental suffocation is highest. After 12 months that risk drops sharply, and sharing a bed with a toddler becomes a family preference question more than a safety one.
Some families enjoy it. Others find that nobody sleeps well. Signs it may be time for a change include frequent night waking for you or your child, a child who cannot fall asleep without you, tension between partners, or a new baby on the way. Keep pillows and heavy bedding away from young toddlers, and never bed share with a toddler and an infant together.
How to Stop Co-Sleeping
If you want your bed back, a gradual plan usually works better than an abrupt one:
Start with the first stretch: put your child down in their own space at bedtime, when sleep pressure is highest. Bring them back there after night wakings as often as you can manage.
Move in stages: go from your bed to a crib or mattress in your room, then to their own room.
Keep the routine identical: the same bath, book, song, and phrase every night signal that sleep is coming.
Stay close at first: sit beside the crib or bed, then move your chair a little farther away every few nights.
Be consistent: switching back and forth teaches a child to keep asking. Pick a plan both caregivers can follow.
Expect protest: a few hard nights are normal. Most children adjust within one to two weeks.
Talk to your pediatrician if you are bed sharing because nothing else gets your baby to sleep, if you are so exhausted that you are falling asleep while holding your baby, or if your baby was born early or small. Tell them what your nights really look like. A good pediatrician will help you make a realistic plan and will not judge you.
Reach out, too, if you are feeling very low, anxious, or overwhelmed. Severe sleep loss and postpartum depression often travel together, and both are treatable.
Frequently Asked Questions
What is co-sleeping?
Co-sleeping means sleeping close to your baby. It includes room sharing, where your baby sleeps on a separate surface in your room, and bed sharing, where your baby sleeps on the same surface as you.
Is co-sleeping safe?
Room sharing is safe and recommended. The American Academy of Pediatrics advises against bed sharing with an infant because it raises the risk of sleep-related infant death, especially on soft surfaces or with babies under 4 months.
What is a co-sleeper?
A co-sleeper is a product for keeping a baby close at night. A bedside sleeper is a bassinet that attaches to the adult bed and has its own safety standard. In-bed sleepers sit on the adult mattress and are not recommended for sleep.
At what age is co-sleeping safe?
The AAP’s safe sleep guidance covers the first 12 months, when risk is highest. After the first birthday, the risk of SIDS and suffocation drops sharply, and bed sharing with a toddler is a family choice.
What should I do if I fall asleep with my baby?
Move your baby to their own sleep space as soon as you wake. If you think you might fall asleep while feeding, feed in a bed cleared of pillows and blankets instead of on a sofa or armchair.
How do I stop co-sleeping?
Make the change gradually. Start bedtime in your child’s own sleep space, keep the routine the same every night, stay nearby at first, and return them to their space after night wakings.
