The thought of a baby dying suddenly and unexpectedly is one that keeps parents awake at night, fearing the worst. For years, little was known about sudden infant death syndrome, or SIDS. Babies would die in their sleep, and it was presumed that little could be done to prevent those deaths.
But the mystery surrounding SIDS is not what it once was. Many SIDS deaths are now believed to be accidents caused by unsafe sleep practices. And some are questioning whether the term SIDS remains relevant at all.
SIDS: A 'Diagnosis Of Exclusion'
In Wayne County, Mich., 50 to 60 infants die suddenly and unexpectedly each year, most of them in Detroit.
For the past 11 years, the task of investigating those cases has fallen to Pat Tackitt, a pediatric mortality investigator for the Wayne County Medical Examiner's Office.
When an infant dies, law enforcement will contact her. She'll head out immediately to the family's home, spending anywhere from one to five hours talking with the family, using a doll to help parents re-enact what happened.
American Academy Of Pediatrics Guidelines
Safe Sleep Practices
- Always place babies to sleep on their backs during naps and at nighttime. Because babies sleeping on their sides are more likely to accidentally roll onto their stomachs, the side position is not as safe as the back and is not recommended.
- Don't cover the heads of babies with a blanket or overbundle them in clothing and blankets.
- Avoid letting the baby get too hot. The baby could be too hot if you notice sweating, damp hair, flushed cheeks, heat rash and rapid breathing. Dress the baby lightly for sleep. Set the room temperature in a range that is comfortable for a lightly clothed adult.
- Place your baby in a safety-approved crib with a firm mattress and a well-fitting sheet (cradles and bassinets may be used, but choose those that are JPMA [Juvenile Products Manufacturers Association] certified for safety).
- Place the crib in an area that is always smoke-free.
- Don't place babies to sleep on adult beds, chairs, sofas, waterbeds or cushions.
- Toys and other soft bedding, including fluffy blankets, comforters, pillows, stuffed animals and wedges should not be placed in the crib with the baby. These items can impair the infant's ability to breathe if they cover his face.
- Breast-feed your baby. Experts recommend that mothers feed their children human milk at least through the first year of life.
- The safest place for your baby to sleep is in the room where you sleep. Place the baby's crib or bassinet near your bed (within an arm's reach). This makes it easier to breast-feed and to bond with your baby.

In all, Tackitt has gone to the scene of more than 500 infant deaths — so many, she stopped counting.
In almost all of the cases, Tackitt says, she found that the baby was in an unsafe sleep environment. The baby may have been sleeping face down, may have been covered by a blanket or pillow, or may have gotten lodged between sofa cushions. In some cases, the baby was sleeping with a parent who rolled on top of the infant in the night.
Tackitt says these are all signs of accidental suffocation, not SIDS.
"There are some deaths that we cannot prevent. These are not those deaths," she says. "The vast majority of these are preventable deaths. There's been very, very few that we've seen that could not be prevented."
SIDS is defined as the sudden death of an infant under 1 year of age, which remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history.
It's often called a "diagnosis of exclusion," meaning it's the diagnosis that's given when everything else has been ruled out. But, Tackitt says, often the term SIDS comes up prematurely.
"We find that in many cases, families have been told from the time the ambulance drove up to the time that the clergy saw them in the emergency room ... that this is going to be a SIDS death," Tackitt says. "All that means is, 'We don't know.' Why would we start out saying 'we don't know,' when we haven't even looked yet?"
Some would argue that a SIDS diagnosis offers compassion in a moment of distress, and a way to avoid blaming parents amid the tragedy.
Wayne County Chief Medical Examiner Carl Schmidt disagrees.
"I think that's cruel," Schmidt says. "I think actually sitting down with a parent and telling them what happened is much more humane than trying to obscure the reasons why that infant actually died. Most people really want to know what happened, so they won't do it again."
In Wayne County, it's been four years since they last signed out a death as SIDS. And that's true elsewhere, too.
The 'Back To Sleep' Campaign
At Children's National Medical Center in Washington, D.C., pediatrician Rachel Moon says it's been several years since they've seen what she calls a "true SIDS case" in the District.
"All the babies who died suddenly and unexpectedly have all died in unsafe sleep environments," Moon says. "These are all cases that could have been prevented."
Moon chairs the American Academy of Pediatrics Task Force on SIDS. In 1992, it was the academy that came out with the recommendation that babies be placed on their backs to sleep, not on their stomachs.
Baby Sleep Positions And SIDS Rates
In 1992, the American Academy of Pediatrics recommended that babies sleep on their backs to prevent accidental deaths. As the number of babies sleeping on their backs has increased, SIDS cases have decreased.
About a quarter of parents in the U.S. say they don't put their babies on their backs to sleep, and among African-Americans, it's about half. According to statistics, African-American babies die of SIDS at a rate twice that of whites.
Moon has been researching why so many people disregard the recommendations. She's found everything from misconceptions about the risks of choking to distrust of doctors to confusion and skepticism.
"What's happening is, you tell people that SIDS is when a baby dies and you don't know why. So then when you tell them they should put their baby on the back, sometimes they turn to you and say, 'Well, wait a second, how can you tell me that putting my baby on the back is going to help prevent this thing that you don't know what causes it?' "
Asked if she can imagine dropping the term "SIDS" at some point, she says, "Oh yeah, I can imagine a time when we just talk about safe sleep. And I think we're starting to get there. I think if people know something's preventable, and they can visualize it happening, then they're more likely to take steps to try to prevent it."
For now, though, Moon says, SIDS is a term people are familiar with. So she'll continue to talk about "SIDS prevention."
She does also believe that there are some true SIDS cases out there — cases in which babies were on their backs, alone in their cribs with nothing else in the crib. But, she says, those cases are very rare.
Can A Simpler Message Save Lives?
In Baltimore, public health officials have replaced the term "SIDS" with these ABCs: Alone. Back. Crib.
In literature distributed in hospitals and in public service announcements, there is almost no mention of SIDS, but rather the message "Sleep Safe." They urge parents to share a room with their baby, but not a bed. They tell parents that the safest sleeping position for a baby is on his or her back, and that a baby is not more likely to choke while on the back. And they emphasize the importance of a clean and clear crib, free of blankets, pillows and toys.

On a national level, the Centers for Disease Control and Prevention is piloting a Sudden Unexpected Infant Death case registry in several states. The goal is to create systems that allow people to more comprehensively describe the circumstances and events surrounding sudden infant deaths.
The pilot project followed a study that found great inconsistency in how SIDS deaths are reported.CDC senior scientist Carrie Shapiro-Mendoza led that study, which looked at two years of SIDS-coded death certificates. She found that in a third of the deaths, SIDS was not explicitly reported by the certifier, raising questions about whether the certifier meant for the deaths to be counted as SIDS.
Instead of the term SIDS, the certifiers used other terms, including "sudden infant death" and "sudden unexpected death in infancy." Some had accompanying notes pointing to unsafe sleep environments. Still, because of the way death certificates are coded, they became part of the national SIDS statistic.
Shapiro-Mendoza also found that SIDS can mean different things to different people. She points out that certifiers have varying levels of education.
"In some large metropolitan areas, for instance, you may have a medical examiner who is a board-certified pediatric pathologist," she says. "In other smaller counties or jurisdictions, you may have an elected official, coroner, and he may have no medical background."
The report concludes that nationally established guidelines for infant death scene investigations would help in the reporting and classification of infant deaths, and that in turn could help with identifying trends.
"If we understand the mechanisms that caused these deaths, if we can actually explain why they occurred, we can hopefully prevent these deaths," Shapiro-Mendoza says.
