Safe Sleep for Babies: Reducing the Risk of SIDS and Sleep-Related Deaths

Always place babies on their back to sleep, alone, in a firm flat crib with no soft bedding, bumpers, or positioners. Room-sharing without bed-sharing for at least 6 months is recommended by the AAP.

The ABCs of safe sleep

The AAP's 2022 safe sleep guidance is organized around three core principles 1:

  • Alone: babies should sleep alone — not with adults, siblings, or pets. Room-sharing (the baby's sleep surface in the parents' room) is recommended for at least the first 6 months as it appears to reduce SIDS risk, but this is distinct from bed-sharing (sharing the same sleeping surface).
  • Back: every sleep, including naps, should be on the back. Side sleeping is not safe. Once a baby can roll from back to front and back again independently, they can be left in whatever position they roll to, but should still be placed on their back to start.
  • Crib (or approved sleep surface): a firm, flat mattress in a crib, bassinet, or play yard that meets current Consumer Product Safety Commission (CPSC) safety standards — with a fitted sheet only, no loose bedding, no bumper pads, no positioners, no pillows. Any inclined surface greater than 10 degrees is not recommended 1.

What does NOT belong in the sleep space

Soft objects in the sleep environment are associated with increased risk of SUID. This includes 1:

  • Bumper pads or padded crib liners (both mesh and padded)
  • Pillows, blankets, quilts, comforters
  • Stuffed animals and soft toys
  • Sleep positioners or wedges
  • Inclined sleepers: the AAP does not recommend inclined sleep surfaces (greater than 10 degrees) for infant sleep, and multiple products have been recalled following infant deaths

Babies can be dressed in a wearable blanket or sleep sack to stay warm without loose bedding.

Bed-sharing: why the risk is higher than many families realize

Bed-sharing (an infant sleeping in the same bed as an adult) is associated with increased SUID risk, particularly when there is soft bedding, when either adult has consumed alcohol or sedating medications, or when the infant is under 4 months or premature. Risk can be up to 67 times higher when infants sleep with someone on a couch 2.

The AAP recommends against bed-sharing in all circumstances. Families who bring a baby into bed for feeding or comfort are encouraged to return the baby to their own sleep surface before falling asleep.

Other factors that influence risk

Additional factors associated with lower SUID risk include 1:

  • Breastfeeding, which appears protective regardless of where feeding occurs
  • Pacifier use at sleep — offering a pacifier at the start of sleep is associated with reduced SIDS risk; it does not need to be reinserted if it falls out
  • Avoiding overheating — the room temperature should be comfortable for a lightly dressed adult
  • Avoiding smoke exposure before and after birth — both prenatal and postnatal smoke exposure increase risk
  • Immunizations — evidence suggests immunizations may be protective against SIDS
  • Supervised tummy time when awake — builds the strength needed for rolling and does not conflict with back-sleeping

When safe sleep guidance is hard to follow

Some families face barriers to following safe sleep guidance — living situations, exhaustion, cultural practices, and equipment cost are real factors. A conversation with a pediatric provider about the family's specific situation can help identify practical approaches. Many communities have programs that provide safe sleep equipment at no cost. The goal is risk reduction in the context of the family's actual situation.

Common questions

Is it okay for my baby to sleep in a swing or bouncer?

Swings, bouncers, and car seats are not approved sleep surfaces for infants. A baby who falls asleep in one should be moved to a firm, flat sleep surface. The inclined position can compromise an infant's airway, particularly in very young babies whose head can fall forward.

My baby only sleeps on their stomach — what should I do?

Back sleeping is uncomfortable for some babies initially but most adapt within a week or two. If an infant consistently rolls to their stomach before they can roll back, and is under the AAP's rollover milestone, this is worth discussing with a pediatric provider. Once a baby can roll both ways independently, they can be left to find their position, but should be placed on their back to start.

Can I use a dock-a-tot or similar lounger for sleep?

Infant loungers and nesting products are not approved sleep surfaces and are not recommended for unsupervised sleep. They have soft sides and are not flat, which are both characteristics associated with increased risk.

Does room-sharing really reduce SIDS risk?

Evidence suggests room-sharing (the infant's sleep surface in the same room as caregivers) is associated with reduced SIDS risk — potentially by as much as 50% compared with sleeping in a separate room. This benefit is distinct from bed-sharing, which carries different risks.

When to get care right away

  • —Baby is found unresponsive — call 911 immediately
  • —Baby is limp, will not wake, or is breathing unusually (too fast, too slow, with pauses)
  • —Baby's lips or skin are pale, blue, or mottled
  • —Any infant who was found in an unsafe sleep position and is not responding normally

Call 911 immediately for any unresponsive infant or an infant who is not breathing normally. Begin infant CPR if you are trained while waiting for help.
