Safe Sleep for Babies: AAP Guidelines Every Parent Should Know

Safe sleep is one of the most important topics for new parents to understand. The way babies are put to sleep matters for their safety. The American Academy of Pediatrics (AAP) provides clear guidelines based on extensive research.

Here's what you need to know.

Important: This article summarizes AAP safe sleep recommendations. For complete guidelines and any specific questions, consult your pediatrician.

The ABCs of Safe Sleep

The easiest way to remember safe sleep basics:

A - Alone: Baby should sleep alone, without other people, pillows, blankets, or soft objects.

B - Back: Baby should be placed on their back for every sleep.

C - Crib: Baby should sleep in a safety-approved crib, bassinet, or play yard with a firm, flat mattress.

These three principles form the foundation of safe infant sleep.

Always on the Back

The AAP recommends placing babies on their back for every sleep, including naps. This applies until baby is 1 year old.

Back sleeping has dramatically reduced SIDS (sudden infant death syndrome) rates since the "Back to Sleep" campaign began in the 1990s.

Some parents worry that back sleeping will cause choking if baby spits up. The AAP addresses this directly: healthy babies placed on their backs are not more likely to choke. Their anatomy and airway reflexes protect them.

Once your baby can roll both ways on their own (back to tummy and tummy to back), you don't need to reposition them if they roll during sleep. But always start them on their back.

Firm, Flat Sleep Surface

Babies should sleep on a firm, flat mattress covered only by a fitted sheet. The mattress should be designed for the specific crib, bassinet, or play yard being used.

Avoid: Soft mattresses, pillow-tops, memory foam, waterbeds, couches, armchairs, and adult beds.

The sleep surface should be flat, not inclined. The AAP recommends against using inclined sleepers, as they've been associated with infant deaths and have been recalled.

Nothing Else in the Sleep Space

The sleep area should have only the baby and a fitted sheet. Keep out:

Pillows, blankets and quilts, bumper pads, stuffed animals, sleep positioners, and any soft objects.

These items, while they may seem cozy, create suffocation and entrapment risks.

What about keeping baby warm? The AAP recommends using a wearable blanket or sleep sack instead of loose blankets. Dress baby appropriately for the room temperature. Overheating is also a risk factor.

Room Sharing Without Bed Sharing

The AAP recommends that babies sleep in the same room as parents, but on a separate sleep surface, for at least the first 6 months, ideally the first year.

Room sharing makes it easier to feed, comfort, and monitor baby. It's associated with reduced SIDS risk.

Bed sharing (baby sleeping in the same bed as parents) is not recommended due to suffocation and entrapment risks. This is especially important if parents smoke, have consumed alcohol, are taking sedating medications, or baby is under 4 months old or was premature.

If you're worried about falling asleep while feeding, feed in your bed rather than on a couch or armchair. If you do fall asleep, move baby to their own sleep space as soon as you wake. Couches and armchairs are particularly dangerous for infant sleep.

Additional AAP Recommendations

Avoid overheating: Keep the room at a comfortable temperature. Baby shouldn't feel hot to the touch or be sweating.

Breastfeeding: Breastfeeding is associated with reduced SIDS risk. If breastfeeding, the AAP recommends continuing as long as you and baby choose.

Pacifier: Consider offering a pacifier at sleep time once breastfeeding is established (usually around 3 to 4 weeks). Pacifier use during sleep is associated with reduced SIDS risk.

Smoke-free environment: Don't smoke during pregnancy or around baby. Keep baby away from secondhand smoke.

Prenatal care: Get regular prenatal care during pregnancy.

Vaccinations: Keep baby's vaccinations current. Evidence suggests immunizations reduce SIDS risk.

Avoid products not designed for sleep: Swings, car seats, strollers, and similar devices aren't designed for prolonged sleep. If baby falls asleep in one, move them to a safe sleep surface as soon as practical.

What About Swaddling?

Swaddling can help soothe young babies. If you swaddle:

Stop swaddling when baby shows signs of rolling (typically around 2 months). Swaddle with hips loose to allow leg movement. Make sure swaddle doesn't cover the face. Always place swaddled baby on their back.

Common Questions

Can I use a baby monitor instead of room sharing? A monitor can provide awareness, but it doesn't replace the protective effect of room sharing. The AAP recommends room sharing regardless of monitor use.

What if baby only sleeps on their tummy? Always place baby on their back. If they're uncomfortable, try other soothing methods. Talk to your pediatrician if you're having difficulty.

Are all cribs safe? Use a safety-approved crib that meets current safety standards. Check for recalls. Don't use cribs with drop sides, missing hardware, or other damage.

Tracking Sleep Safely

When you track your baby's sleep, you're building awareness of their patterns. This helps you establish routines and recognize changes.

Safe sleep is about the sleep environment, not the schedule. Track when and how long baby sleeps, but remember that where and how they sleep matters most for safety.
