For the safest sleep, your baby should sleep in a crib, bassinet, or play yard placed in your bedroom for at least the first six months. This practice, known as room-sharing, can reduce the risk of Sudden Infant Death Syndrome (SIDS) by up to 50%. The key rule is simple: your baby should sleep alone, on their back, in a bare crib.
Bringing a new baby home is a wonderful experience, but it also means a lot of new questions. One of the biggest questions is where should babies sleep at night. It seems simple, but the answer has changed a lot over the years. You want to do what is best for your baby, and you also want to get some sleep yourself.
The good news is that safe sleep recommendations are clear and based on years of research. Experts like the American Academy of Pediatrics (AAP) have guidelines that are easy to follow. This guide will walk you through everything you need to know. We will cover the safest places, the products you need, and the common mistakes to avoid.
Your baby’s sleep environment is the most important piece of the puzzle. Follow these steps to create a safe space for your little one to rest. You will gain confidence knowing you are reducing the risk of SIDS and accidental suffocation.
Key Takeaways
- Room-share for six months: The AAP recommends your baby sleeps in your room, in their own space, for the first 6-12 months to reduce SIDS risk.
- Use a firm, flat surface: Always place your baby on a firm mattress with a fitted sheet. Avoid soft surfaces like couches or adult beds.
- Keep the crib bare: Remove pillows, blankets, bumpers, and stuffed animals. A bare crib is the safest crib.
- Always place baby on their back: This is the single most effective way to prevent SIDS. Do this for every sleep, nap and night.
- Never use sleep positioners or wedges: These products are not safe and have been linked to suffocation risks. The FDA warns against them.
- Know when to transition: Move your baby to a crib when they can roll over or outgrow their bassinet. Always follow the weight and height limits.

The Gold Standard: Room-Sharing
When you ask experts where should babies sleep at night, their first answer is usually your bedroom. This is called room-sharing. It means your baby sleeps in a crib, bassinet, or play yard right next to your bed. It is very different from bed-sharing, which is when your baby sleeps in your adult bed.
Why Room-Sharing Works
Room-sharing is strongly linked to a lower risk of SIDS. Studies show it can lower the risk by as much as 50%. The reasons are not fully understood, but experts have a few ideas. Your baby is more likely to be in a safer sleep position. You are also more aware of your baby’s sounds and movements. You can easily check on them without getting up.
How Long Should You Room-Share?
The AAP recommends room-sharing for at least the first six months. Ideally, you should do it for the first year. This is the period when the risk of SIDS is highest. Six months is the absolute minimum for many families. Try to stick with it as long as you can. It makes nighttime feedings and check-ins much easier.
Setting Up Your Room-Share Space
Place the crib or bassinet close to your bed, but not too close. You want your baby to have their own separate sleep area. Make sure there are no gaps between the mattress and the side of the crib. Keep the area around the sleep space clear of cords from blinds or lamps. This setup is safe and convenient.
The ABCs of Safe Sleep
If you forget everything else, remember these three letters. They form the foundation of all safe sleep practices. They tell you exactly where should babies sleep at night and how they should be placed. The ABCs stand for Alone, Back, and Crib.
- A is for Alone: Your baby should sleep in their own space. No sharing beds, couches, or chairs. No stuffed animals or pillows in the crib.
- B is for Back: Always place your baby on their back for every sleep. This includes naps and nighttime. This position is proven to keep airways clear.
- C is for Crib: Use a safe, approved crib, bassinet, or play yard. The surface must be firm and flat. A crib meets strict safety standards.
Why Back Sleeping is So Important
Before the “Back to Sleep” campaign, many babies slept on their stomachs. This led to a much higher rate of SIDS. When babies sleep on their backs, they are less likely to overheat or rebreathe the air they just exhaled. This keeps oxygen flowing to their brain. It is the single most important step you can take.
What About Tummy Time?
Tummy time is very important for your baby’s development. It strengthens their neck, back, and arm muscles. But tummy time is for when your baby is awake and you are watching them. Never use tummy time as a reason to put your baby on their stomach to sleep. The two activities are completely separate.
The “Bare Is Best” Rule for the Crib
A cozy-looking crib with a soft blanket and a plush bumper might look cute, but it is not safe. The rule for where your baby sleeps is simple: bare is best. This is the safest possible sleep environment. A bare crib has nothing inside except a fitted sheet on a firm mattress.
Items to Avoid in the Crib
Many common nursery items are actually safety hazards. You should not put any of the following in the crib with your baby:
- Soft bedding: No pillows, comforters, or quilts. They can cover your baby’s face.
- Bumper pads: These are a suffocation and entrapment risk. The AAP strongly advises against them.
- Stuffed animals: Keep them out of the crib entirely. They are not toys for sleeping.
- Sleep positioners: These wedges are dangerous and have caused deaths. The FDA warns against them.
- Loose blankets: Instead of a blanket, use a sleep sack or wearable blanket to keep your baby warm.
Keeping Your Baby Warm Without Blankets
You might worry your baby will be cold without a blanket. The solution is to use a sleep sack. This is a wearable blanket that your baby wears like a little sack. It keeps them warm without covering their face. You can also dress them in one extra layer of clothing than you would wear yourself. A onesie and footed pajamas are often enough.
Where Should Babies Sleep at Night: Bassinet vs. Crib
You have a choice between a bassinet and a full-sized crib. Both are safe options. Your choice often depends on your space and your baby’s size. Both are great answers to the question of where should babies sleep at night.
When to Use a Bassinet
A bassinet is a small sleep space for newborns. They are great for room-sharing because they fit right next to the bed. Most bassinets have weight limits, usually around 15 to 20 pounds. Your baby will outgrow it when they can roll over, push up on their hands and knees, or exceed the weight limit. This usually happens around 3 to 4 months.
When to Move to a Crib
A crib is the most common long-term sleep solution. You can use a crib from day one. It has higher sides and a larger sleeping surface. Cribs have higher weight limits, often up to 50 pounds. The safest time to move your baby from a bassinet to a crib is when they meet the outgrow markers, not based on a specific age.
What About Play Yards?
Play yards, also called pack ‘n plays, are also a safe sleep option. They meet safety standards if used with the firm mattress that comes with them. Do not add extra padding or mattresses. A play yard is very portable, making it great for travel or for keeping baby close while you move around the house.
Common Sleep Safety Mistakes to Avoid
Even well-meaning parents can make mistakes. Knowing what to avoid is just as important as knowing what to do. Let’s look at some common slip-ups that answer the question of where should babies sleep at night incorrectly.
Bed-Sharing
Sharing your adult bed with your baby is very dangerous. Adult beds have soft mattresses, pillows, and heavy blankets. These can all cause suffocation. There are no benefits of bed-sharing that outweigh the risks. The AAP says it is not safe under any circumstances. Remember, room-sharing is safe, bed-sharing is not.
Falling Asleep on a Couch or Chair
This is one of the most dangerous things you can do. Falling asleep with your baby on a couch, armchair, or recliner is extremely risky. Your baby can easily become trapped between the cushions or against your body. It can happen in just a few seconds. If you feel tired, put your baby safely in their crib before you fall asleep.
Using Products That Are Not Approved
Many products claim to reduce SIDS risk. Almost none of them are safe. Stay away from sleep wedges, inclined sleepers, and “anti-roll” pillows. The only safe sleep space is a flat, firm crib or bassinet. If a product is not a bare crib, do not let your baby sleep in it. This includes car seats and swings for extended sleep at home.
Conclusion
Knowing where should babies sleep at night is the first step to peaceful and safe sleep for your whole family. The answer is clear: your baby needs their own flat, firm, and bare space in your room. Follow the ABCs of safe sleep. Room-share for at least six months. Keep the crib empty of all soft items.
These guidelines may feel strict, but they are based on life-saving science. They give your baby the best possible start. You are not alone in this journey. Every parent has questions, and every parent makes adjustments. Trust the experts, follow the rules, and rest easy knowing you are building a safe foundation for your baby’s future sleep habits.
Sleep is precious for everyone. With a safe environment, you can all rest a little better.
Frequently Asked Questions
Where should babies sleep at night for the first few months?
For the first six months, your baby should sleep in a crib, bassinet, or play yard placed in your bedroom. This is called room-sharing and it significantly lowers the risk of SIDS. Your baby should be on their back on a firm, flat surface with no soft bedding.
Is it ever safe for a baby to sleep in a side-sleeper or co-sleeper bassinet?
While some parents like the convenience, the AAP recommends a separate sleep surface. If you use a bedside bassinet, make sure it is securely attached to your bed with no gaps. The mattress must be firm and flat. Your baby must still have their own space.
How can I keep my baby warm without blankets in a bare crib?
Dress your baby in a sleep sack or a wearable blanket. This keeps them warm without covering their face. You can also use footed pajamas and a onesie. A general rule is to dress your baby in one more layer than what you are wearing to bed.
What if my baby falls asleep in a car seat or swing?
Car seats, swings, and bouncers are not safe for unsupervised sleep. If your baby falls asleep in one, move them to a firm, flat surface as soon as possible. These devices have an incline that can cause breathing issues. Use them only for travel or supervised awake time.
When should I move my baby from a bassinet to a crib?
Move your baby when they reach the bassinet’s weight limit, can roll over, or start pushing up on their hands and knees. These are safety milestones. Do not wait for a certain age. A full-sized crib will be a safer option once your baby is more mobile.
Where should babies sleep at night if I am breastfeeding?
You can still room-share while breastfeeding. Place the crib or bassinet right next to your bed for easy access. The AAP says this is the safest way to breastfeed at night. Just do not bring your baby into your bed to sleep. Room-sharing makes feeding convenient without the risks of bed-sharing.
