The safest place for your baby to sleep is in a crib, bassinet, or play yard in your room for the first six months. Room-sharing reduces SIDS risk by up to 50% while keeping baby close for feeds and comfort. Always place baby on their back on a firm, flat mattress with no loose bedding or soft objects.
You’ve just brought your little one home, and now the question hits you: where should baby sleep? It’s one of the first big decisions new parents face. Between all the advice from grandparents, friends, and online forums, it’s easy to feel overwhelmed. But don’t worry—we’ve gathered the latest expert recommendations from the American Academy of Pediatrics (AAP) to give you clear, simple answers.
Sleep safety isn’t just about choosing a product. It’s about where you place that product, how you set it up, and what habits you build from day one. Whether you’re planning to use a bassinet, a pack-n-play, or a full-size crib, the core principles stay the same. In this guide, we’ll walk through every option, explain the safest choices, and help you feel confident about where should baby sleep from newborn through the first year.
Key Takeaways
- Room-sharing is recommended: Keep your baby’s sleep space in your bedroom for at least the first six months. This lowers the risk of SIDS and makes nighttime care easier.
- Baby needs a separate, flat sleep surface: Use a crib, bassinet, or portable play yard with a firm mattress. Never share a bed with your baby.
- Always place baby on their back: Back sleeping is the most important behavior to reduce SIDS. Do this for naps and nighttime sleep.
- Keep the sleep area bare: No pillows, blankets, bumper pads, or stuffed toys. Dress baby in a sleep sack or wearable blanket instead.
- Choose a safe mattress and fitted sheet: The mattress should be firm and fit snugly in the crib. Use only a tight-fitting sheet designed for that mattress.
- Watch for hazards like overheating and soft surfaces: Avoid sleep on sofas, armchairs, or adult beds. Keep room temperature comfortable and dress baby in one extra layer than you would wear.
- Transition to a crib when baby outgrows bassinet: Most bassinets have weight limits (15-20 lbs) or when baby can push up. Move to a crib in your room until they are at least 6 months old.

The Number One Rule: Room-Sharing Without Bed-Sharing
The AAP recommends that babies sleep in their parents’ bedroom—but in their own separate sleep space—for at least the first six months, and ideally up to a year. Room-sharing can cut the risk of SIDS by as much as 50%. It also makes nighttime feedings and check-ins easier without you having to stumble down the hall.
Why Not Bed-Sharing?
Bed-sharing—where baby sleeps in the same bed as an adult—dramatically increases the risk of suffocation, entrapment, and SIDS. Even if you think you’re a light sleeper, accidents can happen. If you fall asleep while feeding on a couch or armchair, the risk skyrockets. Instead, place baby back in their bassinet or crib right after feeding.
How to Set Up Room-Sharing
Place your baby’s crib or bassinet close to your bed—within arm’s reach if possible. Some parents use a bedside sleeper that attaches to the adult bed but keeps baby on a separate, firm surface. Make sure there are no gaps between the mattress and the side of the co-sleeper. Keep pillows and blankets away from baby’s space.
Choosing the Right Sleep Surface: Crib vs. Bassinet vs. Play Yard
When deciding where should baby sleep, the surface matters more than the specific brand. All safe sleep surfaces share three features: a firm mattress, a snug-fitted sheet, and no soft bedding.
Bassinet for Newborns
A bassinet is a great first option because it’s small, portable, and fits right beside your bed. Most babies can use a bassinet until they start rolling over (around 3–4 months) or reach the weight limit (usually 15–20 lbs). Look for one with a firm, flat mattress and mesh sides for airflow. Never add extra padding or inserts.
Full-Size Crib
A crib is the standard long-term sleep space. From the start, you can use a crib in your room. When baby outgrows the bassinet, transition them to a crib in your room until at least 6 months of age. Cribs must have a firm mattress that fits tightly around the edges—no more than two fingers’ width of space. Lower the mattress height as baby grows to prevent climbing out.
Play Yards and Portable Cribs
Play yards (like Pack ’n Plays) are fine for travel or even as a primary sleep space, provided they meet safety standards. Use only the mattress pad that came with the unit—don’t add an extra mattress. They are typically lighter and easier to move from room to room. Check the weight and height limits set by the manufacturer.
How to Set Up the Perfect Safe Sleep Environment
Once you’ve chosen the piece of furniture, the real work is inside: keep it bare. That’s the golden rule. A bare crib reduces suffocation risks. Here’s what to include (and not include) in your baby’s sleep space.
The Bunk Bed Checklist
- Firm mattress covered with a tight-fitting sheet
- No pillows for babies under 12 months
- No blankets for babies under 12 months—use a wearable blanket or sleep sack
- No bumper pads, stuffed animals, or toys
- No crib wedges or positioners (these are not safe despite some claims)
- No loose bedding like decorative blankets
If you’re worried about baby getting cold, dress them in one more layer than you would wear comfortably. A sleep sack (wearable blanket) keeps baby warm without loose fabric.
Temperature and Overheating
Keep the room temperature between 68°F and 72°F (20°C–22°C). Overheating is a risk factor for SIDS. Feel baby’s chest or back to check their temperature—if it’s hot or sweaty, remove a layer. Also avoid covering baby’s head during sleep.
Back to Sleep: The Most Important Position
The single most effective way to reduce SIDS is always placing baby on their back for sleep. This applies to naps and nighttime. Don’t worry about baby choking—healthy babies naturally swallow or cough up fluids. Once baby can roll from back to tummy and back again on their own (usually around 6 months), you can let them find their own position. But always start them on the back.
What About Tummy Time?
Tummy time is for awake times only. Put baby on their tummy for short periods during the day to strengthen neck and shoulder muscles. Never use tummy time as a sleep position.
When and How to Transition Sleep Spaces
As your baby grows, the question “where should baby sleep” will evolve. Here’s a typical timeline:
- Newborn to 3–4 months: Bassinet or crib in your room
- 4–6 months: Crib in your room (if baby has outgrown bassinet)
- 6 months onward: Continue room-sharing or start moving to nursery if you prefer (still safe as long as you follow safe sleep guidelines)
Signs It’s Time to Move to a Crib
If your baby starts rolling over in the bassinet, look for a new crib that converts or a standard crib. Also move when they exceed the bassinet’s weight limit. Don’t delay—safety first.
Moving Baby to Their Own Room
Some parents move baby to the nursery at 6 months; others wait until a year. There’s no medical rule that says you must room-share for a full year, but the longer you room-share, the lower the SIDS risk. If you decide to move baby to their own room, do it gradually. Start with naps in the nursery, then transition overnight. Keep the same safe sleep setup.
Common Questions About Baby Sleep Location
Can baby sleep in a swing or car seat?
No. These are not safe for routine sleep. Babies can fall asleep there, but the angle can cause breathing difficulties. If baby nods off in a swing or car seat, move them to a crib as soon as possible.
What about naps during the day?
Safe sleep rules apply to all sleeps—nap times and nighttime. Always place baby on their back in a safe sleep space. It’s okay to hold baby for a nap sometimes, but never put them on a couch or adult bed.
Conclusion
Knowing where should baby sleep comes down to a few simple principles: room-share without bed-sharing, use a firm flat surface, keep it bare, and place baby on their back. These choices can feel overwhelming when you’re exhausted, but they are the best way to protect your little one. Trust the experts, follow the guidelines, and remember that a safe sleeping environment helps baby (and you) rest better. You’ve got this—one sleepy night at a time.
Frequently Asked Questions
Is it safe for my baby to sleep in a bassinet next to my bed?
Yes, it is safe and recommended. A bassinet allows you to room-share while keeping baby on a separate sleep surface. Make sure the bassinet has a firm mattress and mesh sides. Always place baby on their back with no loose bedding.
When should I move my baby from a bassinet to a crib?
Move your baby when they reach the weight limit of the bassinet (usually 15–20 lbs) or when they start pushing up on their hands and knees or rolling over. Typically this happens between 3 and 5 months. The crib should still be in your room for room-sharing if possible.
Can my baby sleep in a pack ‘n play every night?
Yes, a pack ‘n play (play yard) is a safe sleep space as long as you use the manufacturer-provided mattress pad and fitted sheet. Do not add an extra mattress or padding. Follow the same safe sleep guidelines: firm surface, bare crib, and back sleeping.
What if my baby falls asleep while nursing or bottle-feeding?
If you fall asleep while feeding, it’s safest to feed baby in a bed (not on a couch) and then move them to their own sleep space as soon as you wake up. Try to set a timer or feed with baby in the bassinet if possible. The key is to minimize any soft surfaces near baby.
Is it okay to let my baby nap in a stroller or car seat?
No, routine sleep in a car seat or stroller is not recommended because the semi-upright position can cause breathing issues. If baby falls asleep there, move them to a safe flat surface as soon as you can. Short, supervised naps are less risky but not ideal.
How can I keep baby warm without blankets?
Use a wearable blanket or sleep sack that fits correctly. This keeps baby warm without loose bedding. You can also dress baby in footed pajamas or an extra layer. Keep the room temperature moderate and check baby’s chest for signs of overheating.
