The short answer
Always place your rolling baby on their back to start every sleep. If they comfortably roll both ways on their own, they may remain in the position they choose. Stop swaddling at the first signs of rolling and keep the sleep surface firm, flat, and clear.

Keep in mind
- Start every nap and night sleep on the back.
- A baby who rolls independently both ways can remain in their chosen position.
- Stop swaddling as soon as rolling attempts begin.
- Keep the sleep surface firm, flat, level, and free of loose items.
Why should every sleep begin on the back?
Even after your baby starts rolling, always place them on their back for naps and nighttime sleep. The American Academy of Pediatrics (AAP) recommends this starting position throughout the first year. Side sleeping is not a safe substitute because a baby can unintentionally roll onto their stomach.
There is a difference between the position you put your baby in and the position they move into on their own during sleep. If you put your baby down on their back and later find them on their stomach, what to do depends on whether they can roll independently in both directions.
What if your baby rolls onto their stomach in sleep?
If your baby comfortably rolls from back to stomach and from stomach to back without help, you do not need to turn them over repeatedly throughout the night. They may stay in the position they choose. Always start the next sleep on their back.
If your baby can roll only one way, that independence is not yet established. When you notice them on their stomach, you can gently return them to their back. Learning one direction before the other is common; it does not make a soft or cluttered sleep space any safer.
Why stop swaddling when rolling begins?
Do not wait for a particular month or the first complete roll. Stop swaddling as soon as you see signs that your baby is trying to roll. Some babies begin these movements earlier than you might expect.
A baby who rolls onto their stomach while swaddled may not be able to use their arms to reposition. A properly sized, non-weighted sleep sack that leaves the arms and body free may be an alternative. Avoid weighted swaddles, weighted blankets, and weighted sleepwear.
Make the sleep space safe for rolling
Your baby needs a firm, flat, non-inclined sleep surface with only a snug fitted sheet. Remove pillows, loose blankets, stuffed toys, and crib bumpers. Keeping objects away from the face is especially important as movement increases.
Never add rolled towels, support pillows, or sleep positioners to stop rolling: they can create suffocation or entrapment hazards. Raising the head of the mattress for reflux or adding soft layers is not consistent with safe-sleep advice either.
Why a separate sleep surface matters
Use a crib, bassinet, portable crib, or play yard that meets current U.S. safety standards. The American Academy of Pediatrics recommends room-sharing without bed-sharing, ideally for at least the first six months. An adult bed, couch, or armchair is not a safe infant sleep surface.
If your baby falls asleep in a car seat, swing, or stroller, move them to a firm, flat sleep surface as soon as practical. An approved car seat is essential for traveling in a vehicle, but is not intended as the usual sleep place at home.
When your baby rolls over and cries
A baby may learn to roll onto their stomach before learning how to roll back. If they become upset or stuck during sleep, you can help them onto their back and soothe them with your familiar, calm voice.
During the day, give your awake baby opportunities for supervised floor movement and tummy time to practice motor skills. Sleep time, however, is for safe rest—not rolling practice.
What can you do today?
Before bedtime, check the sleep area: a firm, level mattress, a secure fitted sheet, and no toys or loose bedding. If rolling attempts have begun, stop swaddling. If needed, choose a non-weighted sleep sack that leaves the arms unrestricted.
Put your baby down on their back and keep the soothing routine they know. Dimming the lights, speaking quietly, or singing a short lullaby may be enough. The goal is not to prevent rolling, but to make the space safe for movement.
When should you seek help?
If your baby is struggling to breathe, turns blue, or becomes unresponsive, call emergency services immediately (911 in the United States). These are not symptoms to watch and wait on as a sleep-position question.
Talk with your pediatrician if your baby loses a movement skill they previously had or you have persistent concerns about their movements. One difficult night, or learning a skill at a different time from another baby, does not establish a diagnosis.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Breathing difficulty, blue skin, or unresponsiveness: call 911 immediately.
- Talk to a pediatrician about loss of previously learned movement skills.
