Safe Sleep for Infants

Sudden unexpected infant death is the term for a baby under 1 year old who dies suddenly with no cause that is obvious beforehand. It includes sudden infant death syndrome (SIDS), accidental suffocation and strangulation in a sleep space, and deaths with no clear cause. Most of the practices below lower that risk, and all of them cost nothing to do. They are also why infant sleep is one of the most tightly regulated parts of childcare.

The practices here follow the American Academy of Pediatrics (AAP) 2022 safe sleep policy statement. Your state licensing rules and your program's written policy add detail, and where they are stricter, they win. Federal childcare rules list safe sleep as a required training topic for staff in programs covered by the Child Care and Development Fund.

What You Will Be Able to Do

• Set up a safe sleep space and place an infant in it correctly every time
• Explain why sitting devices, soft items and side sleeping are not safe for sleep
• Decide when to stop swaddling and what to do when an infant starts rolling
• Do sleep checks that actually tell you an infant is well
• Respond when a family asks for something the rules do not allow

Every Sleep, Every Infant

The rule applies to naps as well as long sleeps, on a busy day as well as a quiet one, and to babies who "only sleep" one way at home. Follow these steps each time, for every baby up to 1 year old:

1. Place the infant on their back. Never on the side or stomach, even for a short nap.
2. Use a crib, bassinet or play yard with a firm, flat, level surface. A firm surface does not indent when the baby lies on it.
3. Use only a fitted sheet made for that mattress.
4. Keep the sleep space bare. Nothing else goes in with the baby.
5. Give each infant their own sleep space. Never put two babies in one crib, and never let a baby sleep on a couch, armchair, adult bed or cushion.
6. Keep the baby's face and head uncovered.
7. Check that the crib is sound. Cribs in childcare must meet current federal crib standards, and drop-side cribs are not allowed.

Back sleeping does not raise the risk of choking. Healthy babies have a gag reflex that protects the airway, and the AAP recommends the back position for all healthy infants. Side sleeping is not a safe middle ground, because a baby on their side can roll to their stomach.

What Stays Out of the Crib

The federal Safe Sleep for Babies Act made inclined sleepers and padded crib bumpers banned hazardous products, no matter when they were made. If a family brings one in, do not use it. The law does not cover non-padded mesh liners, but the AAP advice is a bare crib, so leave those out as well.

Warning: Products sold as reducing SIDS, including home monitors, have no evidence behind them. They do not replace safe sleep practices or your own checks.

When an Infant Falls Asleep Somewhere Else

Babies fall asleep in car seats, strollers, swings, carriers and bouncers. These are sitting devices. A young baby does not have the neck strength to lift a heavy head, so when the body slumps, the chin can drop to the chest and narrow the airway. That can happen with no sound and no struggle.

If a baby falls asleep in one of these, move them to a firm, flat sleep space on their back as soon as you can. Take them out of the car seat when you arrive, even if they will wake up. The same goes for a baby who falls asleep at the bottle or in your arms: finish, then lay them in the crib on their back.

Rolling and Swaddling

Always place the baby on their back to start. Once a baby can comfortably roll both ways, you do not need to turn them back over if they roll during sleep. The sleep space still needs to be bare, because a rolling baby can end up with their face against anything soft.

Swaddling does not reduce SIDS risk. If your program allows it at all, follow these limits:

• A swaddled baby always goes down on their back.
• Stop swaddling as soon as the baby shows signs of trying to roll. That usually happens at 3 to 4 months, but it can come earlier. A swaddled baby who rolls to the stomach may not be able to lift or turn their head.
• Never use a weighted swaddle.

Many states and programs do not allow swaddling in group care, so ask before you do it.

Pacifiers

A pacifier at sleep time is linked with a lower risk of SIDS, even if it falls out after the baby is asleep. You do not need to put it back in. For a baby who is breastfed, the AAP advises waiting until breastfeeding is well established. Ask the family what they want, and check your program's rule on written permission. Never hang a pacifier around the neck or clip it to clothing during sleep, and never tie it to the crib.

Warm Enough, Not Too Warm

Overheating is linked with a higher risk of sleep-related death. The AAP does not set a room temperature. Use the baby instead:

• Dress the baby in about one layer more than an adult would wear to be comfortable in that room.
• Do not use a hat indoors.
• Check for sweating, a hot chest or flushed skin, and remove a layer if you see any of them.

A state or program may set a room temperature range for your space. If it does, follow it.

Sleep Checks

Your state licensing rule sets how often you must check sleeping infants. Many rules use every 15 minutes, some programs use every 10 or more often, and some rules require you to record each check. Your rule is the one that counts. Whatever the interval, a monitor does not replace going to the crib and looking.

At each check, stand close enough to see that:

1. The baby's chest is rising and falling.
2. The baby's skin looks a normal color.
3. The face and head are uncovered.
4. Nothing has entered the sleep space.
5. The baby is not sweating or too hot.

Then write the time and your initials on the sleep log if your program uses one. Keep the room bright enough to see skin color. A room so dark you cannot see the baby is too dark to supervise.

Warning: If a baby is not breathing or does not respond, shout for help, call 911 and start infant CPR. CPR needs hands-on training and a current card, and reading does not qualify you.

When a Family Asks for Something Else

Parents often say their baby only sleeps on the stomach, in a swing, or with a blanket. They are usually tired and telling you the truth. Stay kind and firm:

1. Thank them for telling you what works at home.
2. Explain that your program follows safe sleep rules for every baby, every time, and that you are not able to change this.
3. Offer what you can do, such as a familiar routine, a pacifier if allowed, or a wearable blanket.
4. Tell your director and record the conversation.

Medical exceptions are rare. Some states accept a different position only with a signed order from the baby's health care provider, kept in the file and known to all staff. Your state rule and director decide that. You do not change a baby's sleep position on your own, and a parent's request alone does not change it.

Awake Time Matters Too

Babies who are awake and watched by an adult need tummy time. It builds the neck, shoulder and arm strength that helps them roll, and it limits flat spots on the head. Start soon after birth with short periods several times a day, and work up to at least 15 to 30 minutes a day by about 7 weeks of age. If the baby falls asleep during tummy time, move them to their back in the crib.

Common Mistakes

Check Your Understanding

1. A 4-month-old arrives asleep in an infant car seat. Her father says she was up all night and asks you to let her finish her nap in the seat. What do you do?

Thank him, then move her to her crib on her back. Sitting devices are not for routine sleep. If she wakes, you comfort her and help her settle again.

2. A 7-month-old who rolls both ways easily flips to his stomach during a nap. What do you do?

Nothing needs to change as long as the crib is bare and his face is clear. Keep placing him on his back at the start of each sleep, and keep doing your checks.

3. A 10-week-old starts rocking side to side in her swaddle and getting a shoulder off the mattress. What do you do?

Those are signs she is trying to roll. Stop swaddling and tell your lead teacher and the family. A wearable blanket with her arms free is a safer choice if your program allows it.

4. A grandmother brings a soft quilt she made and asks you to tuck it around the baby at nap time. What do you say?

Thank her and explain that nothing can go in the crib except the fitted sheet. Offer to keep the quilt in the baby's cubby or to use it for floor play when the baby is awake and watched.

Key Takeaways

• Back, every sleep, on a firm, flat surface, up to 1 year old
• A bare sleep space means a fitted sheet and nothing else
• Move a sleeping baby out of a sitting device as soon as you can
• Stop swaddling at the first signs of rolling, and never use weighted products
• Your state sets the sleep check interval, and a monitor never replaces looking
• A family's preference does not change the rule, so stay kind and involve your director
