The latest on safe infant sleep from the CDC: What 2026 parents need to know
The latest CDC report shows that decades of progress in infant safe sleep that Americans had been making has effectively stalled.
SUID rates fell sharply in the 1990s, from 154.6 to 93.9 deaths per 100,000 live births, according to the CDC. This means that the most recent figure available, 93.6 in 2024, is essentially the same as it was 25 years ago.
The report published September 2026 in CDC's Morbidity and Mortality Weekly Report (MMWR), examined 4,861 sudden unexpected infant deaths (SUIDs) from 2020 through 2024.
It found that nearly three in four babies who died suddenly and unexpectedly in a new CDC analysis were in a sleep setting that safe-sleep guidance warns against.
SUID takes the lives of about 3,400 U.S. babies under age 1 every year. The term covers sudden infant death syndrome (SIDS), accidental suffocation and strangulation in bed, and deaths with no determined cause.
An analysis that works towards SUID prevention
The new analysis draws on CDC's SUID and Sudden Death in the Young (SDY) Case Registry, which captures about two in five U.S. SUIDs, with the objective to use data about SUID and SDY trends and characteristics to carry out actions to reduce future deaths.
Examples of these activities include:
Educating parents and caregivers about safe sleep for babies.
Training hospital staff on safe sleep recommendations.
Supporting safe sleep recommendations in childcare centers.
Where and how infants were sleeping
The first few months are the riskiest window: two-thirds of deaths happened before a baby turned 4 months old. This is also when parents are the most exhausted, and likely to make mistakes. This makes education paramount.
The American Academy of Pediatrics (AAP) recommends that babies sleep on their backs, alone, on a flat, firm surface like a crib or bassinet, with no soft bedding.
Most infants in the registry were found in conditions that broke one or more of those rules.
Sleep environment when found | Share of SUIDs |
In an adult bed or futon | 57% |
In a crib, portable crib or bassinet | 21% |
On a chair or couch | 9% |
Soft bedding present | 78% |
Sharing a sleep surface with a person or animal | 59% |
On stomach or side (not on back) | 46% |
Airway fully obstructed | 28% |
It’s important to note that these factors overlap, so one baby can count in several rows. One factor that stands out is sharing an adult bed. More than half of all babies were found in one, nearly three times as many as were found in a crib.
The AAP's Safe Infant Sleep Guidelines for 2026
The American Academy of Pediatrics' (AAP) updated its parent guide this September. Here are the essentials parents need to know:
Back is best, every single time your baby falls asleep: Place your baby on their back for every nap and every night. Remember, side-sleeping is just as risky as stomach-sleeping.
A firm, flat surface: Use a crib, bassinet, or play yard that meets CPSC (Consumer Protection Safety Commission) standards. Any surface inclined more than 10 degrees isn't safe for sleep. If your baby dozes off in a car seat, swing, or carrier, move them to a flat sleep space as soon as you can.
Room-share, don't bed-share: Keep your baby's sleep space in your room for at least the first six months, as the AAP purports this can lower SIDS risk by as much as 50%. But avoid bed-sharing, and never fall asleep with your baby on a couch or armchair, where the risk of sleep-related death is up to 67 times higher.
Keep the sleep space bare: Use a fitted sheet only—no pillows, blankets, bumpers, or toys. Skip weighted blankets, sleepers, and swaddles, too.
Prevent overheating: Dress your baby in no more than one layer more than you're wearing. Skip hats indoors, as well as checking for sweating, flushed skin, or a hot chest while your baby is sleeping.
Add extra protection layers: Feeding breastmilk, offering a pacifier at naps and bedtime, getting regular prenatal care, keeping your home smoke- and vape-free, and staying current on vaccines are all linked to a lower SIDS risk.
Don't rely on monitors or devices marketed to SIDS: There's no evidence that home cardiorespiratory monitors or wearable wellness devices reduce SIDS risk, so you should never consider them a substitute for safe sleep practices.
What parents and caregivers can take away
Every time your baby sleeps, including napping, the AAP recommends:
Back: Place the baby on their back to sleep.
Alone: Use a sleep surface the baby does not share with adults, other children or pets.
Crib: Use a crib, bassinet or portable crib with a flat, firm mattress and a fitted sheet.
Bare: Keep pillows, blankets, bumpers and soft toys out of the sleep space.
Not on couches or chairs: These were the sleep location in 9% of deaths in this report.
Ensure that not only you are clear on safe sleep practices, but anyone caring for your child. While our registered nurses are well-educated on safe sleep, other caregivers, such as a grandparent or babysitter, may not be. Have a conversation prior to leaving your infant in their care.
It's imporant to remember, safe sleep lowers risk; it does not erase it.
A small group of deaths (2%) had no unsafe sleep factors at all, and about a third of babies had a clear airway. Those cases point to causes researchers do not yet understand, which is why CDC is pushing for more genetic testing. The NIH's Safe to Sleep campaign has more guidance for families.
Safe sleep in 2026 shows American families have stalled progress, with SUID rates barely moving in 25 years.
But the hopeful takeaway is that the vast majority of these deaths involve risks parents and caregivers can control. Placing your baby on their back, alone, on a firm, flat surface with nothing else in the sleep space remains one of the most powerful things you can do for safe sleep.
