SIDS (Sudden Infant Death Syndrome) and SUDI (Sudden Unexpected Death in Infancy) are rare in Australia, with rates dropping dramatically since safe sleep campaigns began in the 1990s, but still affect around 100 babies annually, often linked to modifiable risk factors like unsafe sleep positions, smoking, or co-sleeping, with higher incidence in Indigenous and lower socioeconomic communities. The rate has fallen from over 100 per 100,000 births in the early 90s to roughly 1 in 2,500 births (around 0.4 per 1,000 live births) more recently, though rates vary slightly by year and jurisdiction.
Sharing your bedroom with your baby can reduce their risk of SIDS by up to 50%. Use a new, baby-friendly crib that has a design meant to keep your baby from falling between the side of the crib and the mattress. Make sure your baby's head can't get caught or trapped between the bars of the crib.
Put your baby to sleep your baby on their back ('back to sleep'). Keep your baby's head and face uncovered. Keep your baby's environment smoke-free, before and after birth. Make sure they have a safe sleeping environment, night and day.
Data from the Centers for Disease Control and Prevention (CDC) estimate that about 3,000 infants died from a sudden unexpected infant death, with more than 1 in 3 dying from sudden infant death syndrome (SIDS) in 2022 (the most recent year for which data are available).
Compared to rates in other developed countries, the U.S. SIDS rate remains high.
Countries like Japan, South Korea, and the Nordics have invested heavily in both maternal care during pregnancy and intensive care units after birth. That explains why their neonatal mortality rates are so low.
White noise may also block out excess stimulation and thus, reduce stress levels in babies. But older claims that white noise can reduce the risk of SIDS [7] need more current research.
The peak incidence of SIDS occurs between 1 – 4 months of age; 90% of cases occur before 6 months of age. Babies continue to be at risk for SIDS up to 12 months.
Risk factors for SIDS include:
Tummy Time for a Healthy Baby. Babies need tummy time! Although it does not directly reduce the risk of Sudden Infant Death Syndrome (SIDS), tummy time is an important way to help baby grow and develop.
In Australia, SIDS accounts for approximately 3 deaths in every 10,000 births. Your baby's sleep environment is one of the most important things you will need to manage to make sure they are safe and reduce the risk of SIDS.
Abstract. The American Academy of Pediatrics recommends pacifier/dummy use to help prevent sudden infant death syndrome (SIDS). This recommendation is based on studies that have shown pacifier use reduces the risk of SIDS even under conditions regarded as increasing the risk of SIDS.
Results Fan use during sleep was associated with a 72% reduction in SIDS risk (adjusted odds ratio [AOR], 0.28; 95% confidence interval [CI], 0.10-0.77). The reduction in SIDS risk seemed more pronounced in adverse sleep environments.
The 5-3-3 rule is a loose guideline for structuring a baby's sleep schedule: 5 hours of wake time before the first nap, 3 hours of wake time before the second nap, and 3 hours before bedtime.
Instead the group said, "Although swaddling may be used as a strategy to calm the infant and encourage use of supine position, there is not enough evidence to recommend it as a strategy for reducing the risk of SIDS." A past AAP article explores the controversy over swaddling among doctors, and the AAP provides ...
Health care providers should encourage parents to do the following to reduce the risk of SIDS: Always place your baby on his or her back to sleep—for naps and at night. The back sleep position is the safest, and every sleep time counts.
However, it can happen wherever your baby is sleeping, such as when in a pushchair or even in your arms. It can also happen sometimes when your baby isn't sleeping – some babies have died in the middle of a feed.
SIDS, an unexplained infant death resulting from an unknown medical abnormality or vulnerability is usually classified a natural death. Accidental suffocation, a death resulting from full or partial airway obstruction causing death from oxygen deprivation and increased carbon dioxide, is classified as accidental.
The authors suspect that mothers may be more likely to try to calm restless male infants by putting them to sleep on their stomach, which may contribute to the gender difference in the rate of SIDS.
Studies have found that bedroom heating increases SIDS risk,10 whereas well-ventilated bedrooms and use of a fan is associated with decreased risk of SIDS. These findings suggest that indoor heat is an important risk factor for SIDS.
According to Hauck, this most recent study is unique in that it is the first to determine the duration necessary to provide that protection. “We found that breastfeeding for at least two months reduces the risk of SIDS by almost half, and the longer babies are breastfed, the greater the protection,” says Hauck.
The 2-3-4 rule for baby sleep is a nap schedule framework for babies usually over 6 months old, suggesting wake windows of 2 hours after the first wake-up, 3 hours between the first and second nap, and 4 hours before bedtime, creating two naps and promoting longer nighttime sleep by increasing wake time throughout the day. It's a flexible guideline to build a predictable routine, but parents should adjust it to their baby's cues as every baby is different.
One of the most effective and easiest ways to reduce the risk of SIDS is to place your baby on his or her back to sleep for naps and at night. In the early 1990s, when infant stomach sleeping was more common, almost 5,000 babies died of SIDS each year.
Research shows that room sharing reduces the risk of SIDS and sleep-related infant deaths. It is safer than bed sharing and is safer than having baby sleep in their own room.
