is a pediatric cardiologist in Cincinnati, but when you ask him for his title, he follows it by saying: 鈥淢ost importantly, I鈥檓 Charlie鈥檚 dad.鈥
Hanke remembers the night 13 years ago when Charlie, then 3 weeks old, was fussier than usual, so he picked him up to soothe him back to sleep. With Charlie still in his arms, he sat on the couch, turned on the TV, and nodded off.

鈥淲e were kind of chest to chest, the way you see in pictures a lot,鈥 Hanke said. But he didn鈥檛 realize Charlie鈥檚 airways were blocked. Too young to turn his head, too squished to let out a cry, Charlie died silently. The next morning, Hanke woke up to his worst nightmare. Years of medical school weren鈥檛 enough to prevent Hanke from losing Charlie to accidental suffocation.
, a well-known term that describes unexplained but natural infant deaths resulting from an unknown medical abnormality or vulnerability, is the leading cause of unexpected deaths among infants in the U.S. It has long been among new parents鈥 greatest fears.
Rates for SIDS have declined since the 1990s, but a different cause of infant death 鈥 accidental suffocation or strangulation 鈥 has also been a persistent problem. That national rate for the past decade has hovered between 20 and 25 infant deaths per 100,000 live births, accounting for around a fifth of all unexpected infant deaths, according to the . Accidental suffocations and strangulations aren鈥檛 necessarily happening more often, some experts say; rather, fatality review teams have become better at identifying causes of death.
And the trend remains steady despite decades of public information campaigns imploring parents to take steps to keep their babies safe while sleeping.
In the mid-1990s, the launched its 鈥淏ack to Sleep鈥 campaign, to teach parents to lay infants on their backs to sleep. 鈥淭here were tremendous results after 鈥楤ack to Sleep,鈥欌 said , executive director of , a Connecticut-based nonprofit group focused on safe sleep education. Unexpected infant deaths dipped about 40% from 1990 levels, which was before that campaign launched, according to the CDC. 鈥淏ut then it plateaued,鈥 Jacobson said.
The NICHD eventually broadened this message with other ways to limit risks beyond a baby鈥檚 sleep position with the 鈥溾 initiative.
Some clear warnings from it: Infants shouldn鈥檛 sleep with blankets, stuffed toys, or bumpers that 鈥渃an potentially lead to suffocation or strangulation,鈥 said , program coordinator for in Fort Worth, Texas. They also should sleep in cribs or bassinets 鈥 not on beds with siblings or in parents鈥 arms.

But these public health messages 鈥 contradicted by photos or videos circulating in movies and social media 鈥 don鈥檛 always find traction. Professional photos of infants, for example, too commonly show them peacefully snoozing surrounded by plush animals and blankets. St. John added that parents sometimes have preconceived ideas of how infants’ sleeping spaces should be decorated. 鈥淲hen you think of cribs and nurseries and things like that, you imagine the pictures in the magazines,鈥 St. John said. 鈥淎nd those are beautiful pictures, but it doesn鈥檛 keep your baby safe.鈥
St. John said many parents know that babies should be on their backs to sleep, but warnings about strangulation by blankets or suffocation by sharing a bed with them sometimes fall through the cracks.
For instance, new parents, especially single parents, are more likely to accidentally fall asleep with their infants because of exhaustion, said , a neonatologist at Cincinnati Children鈥檚 Hospital.
The idea that sleeping with one鈥檚 baby is dangerous can also be counterintuitive to a new parent鈥檚 instinct. 鈥淲e feel like being close to them, being able to see them, being able to touch them and feel that they鈥檙e breathing is the best way we can protect them and keep them safe,鈥 said Miller, who is also an assistant professor at the University of Cincinnati鈥檚 Department of Pediatrics.
Organizations across the country are working to help parents better understand the true risks. Hanke and his wife, for instance, channeled their grief into , a nonprofit focused on safe sleep practices for infants. The Hankes also wrote a book, 鈥,鈥 which has sold about 5 million copies. The proceeds are used to continue their educational efforts.
Ohio, where Charlie鈥檚 Kids is based, in 2020 saw 146 , a classification that includes SIDS, accidental suffocation and strangulation, and other instances in which the cause is undetermined. That鈥檚 about a death for every 1,000 live births, according to the . Thirty-six percent of those deaths were attributed to accidental suffocation or strangulation. Nationally, the rate of these unexplained deaths has declined since the 1990s, but, according to the CDC, significant racial and ethnic differences continue.
The particular risks for an infant鈥檚 accidental suffocation in many respects are situational 鈥 and often involve people at the lower end of the income scale who tend to live in close quarters. People who live in a small apartment or motel often share sleep space, said St. John.
Tarrant County has one of Texas鈥 highest rates of infant deaths 鈥 three to four each month 鈥 attributed to accidental suffocation.
So, organizations like the , which serves Fort Worth and parts of Dallas, have been providing free bassinets and cribs to those in need.
County representatives spoke during the state鈥檚 Child Fatality Review Team meeting in May and focused on the prevalence of infant deaths linked to accidental suffocation. For the past decade, data shows, the county has averaged 1.05 sudden unexpected infant deaths per 1,000 births, which is higher than both the state and national averages of 0.85 and 0.93, respectively. During a 15-month period starting in 2022, Cook Children鈥檚 Medical Center saw after they left because of unsafe sleeping environments.
Sometimes parents鈥 decisions are based on fears that stem from their environments. 鈥淧arents will say 鈥業鈥檓 bringing my baby into bed because I鈥檓 afraid of gunshots coming through the window, and this is how I keep my baby safe鈥 or 鈥業鈥檓 afraid rats are going to crawl into the crib,鈥欌 said First Candle鈥檚 Jacobson.
She understands these fears but stresses the broader context of safe sleep.
The key to educating parents is to begin when they are still expecting because they receive 鈥渁 load of information鈥 in the first 24 or 48 hours after a baby is delivered, said , a neonatal-perinatal specialist at in San Antonio. Garza-Cox is also a member of the Bexar County Child Fatality Review Team.
And once a child is born, the messaging should continue. In Connecticut, for instance, First Candle hosts monthly conversations in neighborhoods that bring together new parents with doulas, lactation consultants, and other caregivers to discuss safe sleep and breastfeeding.
And both Tarrant and Bexar counties are placing ads on buses and at bus stops to reach at-risk parents and other caregivers such as children, relatives, and friends. Parents are very busy, Garza-Cox said. 鈥淎nd sometimes, multiple children and young kids are the ones watching the baby.鈥
