Safe Sleep Guidelines for Babies: What Every Parent Should Know.

Bringing home a new baby is exciting—but it also comes with many questions, especially about sleep. Creating a safe sleep environment is one of the most important ways to protect your baby during the first year of life.

The American Academy of Pediatrics (AAP) updated its safe sleep recommendations in 2022 to help reduce the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related infant deaths. Below is a parent-friendly guide to the most important recommendations.

1. Always Place Your Baby on Their Back to Sleep

The safest sleep position for every baby is flat on their back, for every nap and every night.

This recommendation applies even if your baby:

• Was born prematurely
• Has gastroesophageal reflux (GERD)
• Spits up frequently

Many parents worry that babies sleeping on their backs may choke if they spit up. However, research shows this is not true. When babies sleep on their backs, their airway anatomy actually helps prevent milk or stomach contents from entering the lungs.

Should Babies Sleep on Their Side?

No. The AAP does not recommend side sleeping because babies can easily roll onto their stomachs.

What If My Baby Rolls Over?

Once your baby can roll from back to tummy and tummy to back on their own, you don’t need to reposition them during the night. However, you should always place them on their back at the beginning of every sleep until they reach their first birthday.

2. Use a Firm, Flat Sleep Surface

Your baby should sleep on a firm, flat mattress that fits snugly inside a safety-approved crib, bassinet, or play yard.

Avoid:

• Inclined sleepers
• Soft mattresses
• Adult beds
• Recliners
• Sofas
• Car seats for routine sleep

A car seat is designed for travel—not regular sleep. If your baby falls asleep in a car seat, move them to a safe sleep surface as soon as possible once you’ve reached your destination.

3. Keep the Crib Empty

One of the leading causes of accidental suffocation is having soft objects inside the crib.

Your baby’s crib should contain only:

• A firm mattress
• A fitted crib sheet

Do not place:

• Pillows
• Blankets
• Loose sheets
• Stuffed animals
• Sleep positioners
• Nursing pillows
• Crib bumpers

Instead of loose blankets, dress your baby in:

• Footed pajamas
• Wearable blankets or sleep sacks

These keep babies warm while reducing suffocation risks.

4. Share a Room—Not a Bed

The AAP recommends that babies sleep in the same room as their parents for at least the first 6 months, and ideally for the first year.

Room-sharing can reduce the risk of SIDS by up to 50% while making nighttime feedings easier.

However, bed-sharing is not recommended because it significantly increases the risk of:

• Suffocation
• Entrapment
• Accidental overlay
• Sleep-related infant death

If you bring your baby into bed for feeding or comforting, return them to their own sleep space before you fall asleep.

5. Never Sleep with Your Baby on a Sofa or Recliner

Sofas, armchairs, and recliners are among the most dangerous places for infants to sleep.

If you’re feeling sleepy while feeding your baby:

• Feed in your bed rather than on a couch.
• Remove pillows, heavy blankets, and other soft bedding.
• Return your baby to their crib or bassinet as soon as you’re awake.

6. Breastfeeding Helps Reduce SIDS Risk

Breastfeeding offers many health benefits—including lowering the risk of SIDS.

Whether you exclusively breastfeed or combine breast milk with formula, breastfeeding is encouraged whenever possible.

7. Avoid Overheating

Babies don’t need to be bundled in multiple layers.

A simple rule:

Dress your baby in one more layer than you’re comfortable wearing.

Watch for signs of overheating:

• Sweating
• Damp hair
• Warm chest
• Flushed skin

Keep hats and hoods off indoors during sleep.

8. Keep Your Home Smoke-Free

Exposure to cigarette smoke before or after birth significantly increases the risk of SIDS.

For the healthiest environment:

• Don’t smoke during pregnancy.
• Keep your home smoke-free.
• Keep your car smoke-free.
• Ask visitors not to smoke around your baby.

9. Avoid Alcohol and Drugs During Pregnancy and After Birth

Alcohol, marijuana, opioids, and other drugs can increase sleep-related risks by affecting a caregiver’s ability to safely care for a baby—especially during nighttime feedings.

10. Stay Up to Date on Well-Baby Visits and Vaccinations

Routine pediatric appointments allow your baby’s doctor to monitor growth, development, and sleep safety.

Keeping your baby vaccinated according to the recommended immunization schedule has also been associated with a lower risk of SIDS.

11. Don’t Rely on Products That Claim to Prevent SIDS

Many products marketed to parents promise to reduce the risk of SIDS.

Currently, no commercial sleep product has been proven to prevent SIDS, including:

• Sleep positioners
• Wedges
• Anti-roll devices
• Specialized mattresses
• Cardiorespiratory home monitors for healthy babies

Always follow evidence-based safe sleep practices instead.

12. Give Your Baby Daily Tummy Time

Tummy time is essential for healthy development—but only while your baby is awake and supervised.

Benefits include:

• Strengthening neck and shoulder muscles
• Preventing flat spots on the head
• Supporting motor development

Start with just a few minutes several times a day and gradually increase as your baby grows.

13. Swaddling Safety

Swaddling may help calm some newborns, but it does not reduce the risk of SIDS.

If you choose to swaddle:

• Always place your baby on their back.
• Stop swaddling as soon as your baby shows signs of rolling over (often around 2–3 months).
• Ensure the swaddle isn’t too tight around the hips.

Final Thoughts

Following the American Academy of Pediatrics’ safe sleep recommendations is one of the most effective ways to reduce the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related injuries during your baby’s first year.

While every family’s routine is different, simple habits—like putting your baby to sleep on their back, using a firm crib mattress, and keeping the sleep area free of soft objects—can make a life-saving difference.
