Baby sleep dangers revealed in new study as nearly 70% of infant deaths were due to co-sleeping

Allowing babies to sleep outside their cribs or dedicated solo sleep spaces can have life-threatening risks.

That’s according to a recent study by the Centers for Disease Control and Prevention (CDC), which was published in the medical journal Pediatrics.

Among infants who died suddenly, 59.5% were sleeping with someone else at the time.

Around 76% were sleeping in an adult bed and 68.2% were sharing a bed with an adult, the study found.

SIDS LINKED TO BRAIN ABNORMALITY THAT INCREASES BABIES’ RISK IN ‘UNSAFE SLEEP CONDITIONS,’ STUDY FINDS

In 68.3% of the deaths, soft bedding was found in the sleeping area.

The researchers looked at more than 7,500 sudden unexpected infant deaths in 23 U.S. states between 2011 and 2020.

They evaluated the babies’ sleep environments, demographics and other characteristics.

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, joined “Fox & Friends” this week to discuss the dangers associated with unsafe sleep habits.

SIDS BREAKTHROUGH? POSSIBLE SUDDEN INFANT DEATH SYNDROME BIOMARKER IDENTIFIED

While it may seem “natural” for a child to be in bed with a parent, especially among those who are new to parenting, these sleep arrangements can have tragic consequences, the doctor warned. 

Of the 1,300 to 1,500 cases of SIDS (sudden infant death syndrome) each year, almost three-quarters of them were associated with a child sleeping in a bed with a parent, he pointed out.

“You know why? The surface isn’t firm enough,” he said.

“When you sleep, you have a mattress you want to feel comfortable with — but in the crib, [it should be] a very firm mattress,” he added. 

“These are key issues — you don’t want to have your child sleeping on their stomach when they are very young.”

Previous studies have shown that SIDS has something to do with the way the baby is exchanging oxygen and carbon dioxide, Siegel noted.

“It’s also related to what you do when you’re pregnant,” he said. “You don’t want to be smoking, you don’t want to be drinking alcohol. All of that increases the risk of SIDS.”

It’s safest for babies to sleep on their backs or sides until they are 1 year old, Siegel advised.

The American Academy of Pediatrics (AAP) shared specific guidelines on its website to ensure safe sleeping for babies and young children.

Parents and caregivers should place infants on their backs for sleep in their own dedicated sleep space — a crib, bassinet or portable play yard with a firm, flat mattress and a fitted sheet — with no other people in that same space. 

Infants should not be put to sleep on a couch, an armchair, a swing or a car seat.

No loose blankets, pillows, stuffed animals, plush toys, crib bumpers or other soft items should be placed in the child’s sleep space.

The AAP also recommends breastfeeding if possible and that parents should avoid smoking to reduce risk.
