How to Keep Your Sleeping Baby Safe: AAP Policy Explained

More than 3,500 babies in the U.S. die suddenly and unexpectedly every year while sleeping, often due to sudden infant death syndrome (SIDS) or accidental deaths from suffocation or strangulation.In an effort to reduce the risk of all sleep-related infant deaths, the American Academy of Pediatrics’ (AAP) updated policy statement and technical report includes new evidence that supports skin-to-skin care for newborn infants; addresses the use of bedside and in-bed sleepers; and adds to recommendations on how to create a safe sleep environment.Note: All of these recommendations, unless mentioned otherwise, are for babies up to 1 year of age. Talk with your pediatrician if you have questions about any of the recommendations listed.

What You Can Do: Recommendations for Infant Sleep Safety

• Until their first birthday, babies should sleep on their backs for all sleep times—for naps and at night. We know babies who sleep on their backs are much less likely to die of SIDS than babies who sleep on their stomachs or sides. The problem with the side position is that the baby can roll more easily onto the stomach. Some parents worry that babies will choke when on their backs, but the baby’s airway anatomy and the gag reflex will keep that from happening. Even babies with gastroesophageal reflux (GERD) should sleep on their backs.
  • Newborns should be placed skin-to-skin with their mother as soon after birth as possible, at least for the first hour. After that, or when the mother needs to sleep or cannot do skin-to-skin, babies should be placed on their backs in the bassinet. While preemies may need to be on their stomachs temporarily while in the NICU due to breathing problems, they should be placed on their backs after the problems resolve, so that they can get used to being on their backs and before going home.
  • Some babies will roll onto their stomachs. You should always place your baby to sleep on the back, but if your baby is comfortable rolling both ways (back to tummy, tummy to back), then you do not have to return your baby to the back. However, be sure that there are no blankets, pillows, stuffed toys, or bumper pads around your baby, so that your baby does not roll into any of those items, which could cause blockage of air flow.
  • If your baby falls asleep in a car seat, stroller, swing, infant carrier, or sling, you should move him or her to a firm sleep surface on his or her back as soon as possible.

• Use a firm sleep surface. A crib, bassinet, portable crib, or play yard that meets the safety standards of the Consumer Product Safety Commission (CPSC) is recommended along with a tight-fitting, firm mattress and fitted sheet designed for that particular product. Nothing else should be in the crib except for the baby. A firm surface is a hard surface; it should not indent when the baby is lying on it. Bedside sleepers that meet CPSC safety standards may be an option, but there are no published studies that have examined the safety of these products. In addition, some crib mattresses and sleep surfaces are advertised to reduce the risk of SIDS. There is no evidence that this is true, but parents can use these products if they meet CPSC safety standards.
• Room share—keep baby’s sleep area in the same room where you sleep for the first 6 months or, ideally, for the first year. Place your baby’s crib, bassinet, portable crib, or play yard in your bedroom, close to your bed. The AAP recommends room sharing because it can decrease the risk of SIDS by as much as 50% and is much safer than bed sharing. In addition, room sharing will make it easier for you to feed, comfort, and watch your baby.
• Only bring your baby into your bed to feed or comfort. Place your baby back in his or her own sleep space when you are ready to go to sleep. If there is any possibility that you might fall asleep, make sure there are no pillows, sheets, blankets, or any other items that could cover your baby’s face, head, and neck, or overheat your baby. As soon as you wake up, be sure to move the baby to his or her own bed.
• Never place your baby to sleep on a couch, sofa, or armchair. This is an extremely dangerous place for your baby to sleep.
• Bed-sharing is not recommended for any babies. However, certain situations make bed-sharing even more dangerous. Therefore, you should not bed share with your baby if:
  • Your baby is younger than 4 months old.
  • Your baby was born prematurely or with low birth weight.
  • You or any other person in the bed is a smoker (even if you do not smoke in bed).
  • The mother of the baby smoked during pregnancy.
  • You have taken any medicines or drugs that might make it harder for you to wake up.
  • You drank any alcohol.
  • You are not the baby’s parent.
  • The surface is soft, such as a waterbed, old mattress, sofa, couch, or armchair.
  • There is soft bedding like pillows or blankets on the bed.

• Keep soft objects, loose bedding, or any objects that could increase the risk of entrapment, suffocation, or strangulation out of the baby’s sleep area. These include pillows, quilts, comforters, sheepskins, blankets, toys, bumper pads or similar products that attach to crib slats or sides. If you are worried about your baby getting cold, you can use infant sleep clothing, such as a wearable blanket. In general, your baby should be dressed with only one layer more than you are wearing.
• It is fine to swaddle your baby. However, make sure that the baby is always on his or her back when swaddled. The swaddle should not be too tight or make it hard for the baby to breathe or move his or her hips. When your baby looks like he or she is trying to roll over, you should stop swaddling.
• Try giving a pacifier at nap time and bedtime. This helps reduce the risk of SIDS, even if it falls out after the baby is asleep. If you are breastfeeding, wait until breastfeeding is going well before offering a pacifier. This usually takes 2-3 weeks. If you are not breastfeeding your baby, you can start the pacifier whenever you like. It’s OK if your baby doesn’t want a pacifier. You can try offering again later, but some babies simply don’t like them. If the pacifier falls out after your baby falls asleep, you don’t have to put it back in.

What Moms Can Do: Recommendations for Prenatal & Postnatal

• Do not smoke during pregnancy or after your baby is born. Keep your baby away from smokers and places where people smoke. If you are a smoker or you smoked during pregnancy, it is very important that you do not bed share with your baby. Also, keep your car and home smoke-free. Don’t smoke anywhere near your baby, even if you are outside.
• Do not use alcohol or illicit drugs during pregnancy or after the baby is born. It is very important not to bed share with your baby if you have been drinking alcohol or taken any medicines or illicit drugs that can make it harder for you to wake up.
• Breastfed babies have a lower risk of SIDS. Breastfeed or feed your baby expressed breast milk. The AAP recommends breastfeeding as the sole source of nutrition for your baby for about 6 months. Even after you add solid foods to your baby’s diet, continue breastfeeding for at least 12 months, or longer if you and your baby desire.
• Schedule and go to all well-child visits. Your baby will receive important immunizations at these doctor visits. Recent evidence suggests that immunizations may have a protective effect against SIDS.
• Make sure your baby has tummy time every day. Awake tummy time should be supervised by an awake adult. This helps with baby’s motor development and prevents flat head syndrome. See Back to Sleep, Tummy to Play for more information and ways to play with the baby during tummy time.

Don’t Believe Product Claims

• Don’t believe claims that a product can “prevent SIDS.” There is no known way or product to prevent SIDS. Products such as wedges, positioners, and other sleep aids have not been tested for safety or effectiveness. The U.S. Food and Drug Administration, the CPSC, the AAP, and other organizations warn against these products because of the dangers they pose to babies.
• Do not rely on home heart or breathing monitors to reduce the risk of SIDS. If you have questions about using these monitors for other health conditions, talk with your pediatrician.
• There isn’t enough research on bedside or in-bed sleepers. The AAP can’t recommend for or against these products because there have been no studies that have looked at their effect on SIDS or if they increase the risk of injury and death from suffocation.

FAQ – Infant Safe Sleep Recommendations

1. What is the safest sleep position for my baby?

Always place your baby on their back to sleep, for every nap and nighttime sleep, until their first birthday. This significantly reduces the risk of SIDS (Sudden Infant Death Syndrome).

2. Can babies choke while sleeping on their backs?

No. The airway anatomy and natural gag reflex prevent choking. Even babies with reflux (GERD) should sleep on their backs unless advised otherwise by a doctor.

3. Can my baby sleep in a car seat, stroller, or sling?

Only temporarily. If your baby falls asleep in any sitting device, move them to a firm, flat sleep surface as soon as possible.

4. What should (or shouldn’t) be in the crib?

The crib should have only: baby on their back, a firm mattress, and a fitted sheet. No pillows, blankets, toys, bumpers, or soft items – these increase the risk of suffocation.

5. Is bed-sharing safe?

No. Bed-sharing increases the risk of SIDS, especially for babies under 4 months, preterm infants, or if parents smoke or have consumed alcohol or sedatives. Room-sharing (not bed-sharing) is advised.

6. Is it safe to use a pacifier during sleep?

Yes. Pacifiers at nap time and bedtime may reduce the risk of SIDS. If breastfeeding, wait 2–3 weeks until nursing is well-established.

7. How long should babies sleep in the same room as parents?

Keep your baby’s crib or bassinet in your room for at least the first 6 months, ideally up to 1 year. Room-sharing lowers SIDS risk by up to 50%.

8. Is swaddling safe for newborns?

Yes, if done correctly. Always lay swaddled babies on their back. Stop swaddling as soon as your baby shows signs of rolling over.

9. Is skin-to-skin contact after birth recommended?

Yes. Begin skin-to-skin care immediately after birth, ideally for the first hour. Afterward, place baby on their back in a safe bassinet if the mother is sleeping or unavailable.

10. What’s the #1 tip for safe sleep?

Place your baby on their back to sleep, alone, on a firm surface, with no soft items nearby. This is the best way to prevent sleep-related injuries or death.
