Place your baby on their back to sleep from the very beginning for both day and night sleeps. This will reduce the risk of cot death. Do not put your baby to sleep on their side or tummy. Once your baby is old enough to roll over, there's no need to worry if they turn onto their tummy or side while sleeping.
Most SIDS deaths happen in babies between 1 and 4 months old, and cases rise during cold weather. Babies might have a higher risk of SIDS if: their mother smoked, drank, or used drugs during pregnancy and after birth. their mother had poor prenatal care.
The rate of SIDS deaths per 100,000 live births has declined in Australia since the beginning of national public education campaigns about risk factors associated with SIDS in 1991 (AIHW 2012). Between 2007 and 2017 the rate declined from 28 per 100,000 to 6 in 2017, following a peak in 2009 of 32 per 100,000.
SIDS has no symptoms or warning signs. Babies who die of SIDS seem healthy before being put to bed. They show no signs of struggle and are often found in the same position as when they were placed in the bed.
Even though the thought can be deeply unsettling, experts agree that there aren't any warning signs for SIDS. And since SIDS isn't diagnosed until after an infant has died and the death has been investigated, you can't catch SIDS while it's happening and stop it, for instance, by performing CPR.
SIDS occurs between the first month and before the first year of an infant's life. Infants aged 2-4 months endanger greater risk of SIDS, while most deaths occur in infants during the sixth month of their life6.
Researchers have found that an infant who is swaddled – wrapped tightly in a blanket or cloth with their limbs restricted – while placed on their front or stomach to sleep faces a higher risk of SIDS.
Sleep position:
Babies who are used to sleeping on their backs but who are placed on their stomachs or sides for sleep, like for a nap, are at very high risk of SIDS.
White noise reduces the risk of SIDS.
We DO know that white noise reduces active sleep (which is the sleep state where SIDS is most likely to occur).
Sleeping position: Sleeping on the stomach is a major risk factor for SIDS. Side sleeping is also a risk factor because infants may turn to their stomachs after being placed on their sides. One theory is that stomach sleeping increases the risk of the infant rebreathing his or her own exhaled air.
It may be because babies don't sleep as deeply when they have a pacifier, which helps wake them up if they're having trouble breathing. A pacifier also keeps the tongue forward in the mouth, so it can't block the airway.
SIDS is primarily caused by a lack of air ventilation and air circulation. A room that's too hot and stuffy can also be a likely culprit for SIDS. Therefore, turning on a fan in your baby's room is an effective way to help regulate a room's temperature and provide vital air circulation and ventilation.
Dr. Hauck: We don't know for sure why room-sharing without bed-sharing is protective, but we have some theories. One is that the babies are sleeping more lightly because there is more movement around them (so they cannot get into as deep a sleep, which can contribute to the final pathway in SIDS).
After 6-months old, babies are typically able to lift their heads, roll over, or wake up more easily, and the risk of SIDS decreases dramatically. However, 10% of SIDS happens between 6 and 12 months of age and safe sleep recommendations should be followed up to a baby first birthday.
Most SIDS deaths happen in babies between 1 month and 4 months of age, and the majority (90%) of SIDS deaths happen before a baby reaches 6 months of age. However, SIDS deaths can happen anytime during a baby's first year.
SIDS risk by age
The NICHD notes that SIDS is most common when an infant is between 1–4 months old. Additionally, more than 90% of SIDS deaths occur before the age of 6 months old. The risk of SIDS reduces after an infant is 8 months old.
The results showed a positive correlation between temperature and SIDS in 3–12 month-old infants specifically. On days when temperatures were greater than 29 °C, there was a 2.78 times greater chance of sudden infant death than on 20 °C days.
SIDS is not the same as suffocation and is not caused by suffocation. SIDS is not caused by vaccines, immunizations, or shots.
The key risk factors associated with SUDI in Aboriginal and Torres Strait Islander infants are: low birthweight. premature birth. maternal nutrition during pregnancy.
Studies have shown that the increased SIDS risk associated with colder temperatures in the winter can be explained by excessive clothing and overwrapping of infants.
Infants at the age when SIDS occurs quite frequently spend most of their sleep in a stage known as rapid eye movement or REM sleep. This sleep stage is characterized by the dysregulation of various mechanosensory airway and chemosensory autonomous reflexes that are critical for survival (18, 19).
