While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood. When babies sleep face down, they may re-breathe exhaled carbon dioxide.
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.
Scientists in Australia have found that some babies at risk of sudden infant death syndrome, or SIDS, have low levels of an enzyme called butyrylcholinesterase (BChE) in their blood.

SIDS is less common after 8 months of age, but parents and caregivers should continue to follow safe sleep practices to reduce the risk of SIDS and other sleep-related causes of infant death until baby's first birthday. More than 90% of all SIDS deaths occur before 6 months of age.
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.
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).
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.
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.
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.
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).
SIDS is most common at 2-4 months of age when the cardiorespiratory system of all infants is in rapid transition and therefore unstable. So, all infants in this age range are at risk for dysfunction of neurological control of breathing.
Age. Infants younger than 6 months old represent roughly 90 percent of all SIDS-related deaths. It is believed the risk of SIDS peaks between 1 and 4 months. Additionally, preterm infants with low birth weights are considered at higher risk of SIDS.
Babies who are breastfed or are fed expressed breastmilk are at lower risk for SIDS compared with babies who were never fed breastmilk. According to research, the longer you exclusively breastfeed your baby (meaning not supplementing with formula or solid food), the lower his or her risk of SIDS.
Conclusions SIDS can happen at any time of the day and relatively quickly. Parents need to be made aware that placing infants supine and keeping them under supervision is equally important for day-time sleeps.
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.
Babies who usually sleep on their backs but who are then placed to sleep on their stomachs, such as for a nap, are at very high risk for SIDS. Sleep in an adult bed with parents, other children, or pets; this situation is especially dangerous if: The adult smokes, has recently had alcohol, or is tired.
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.
A B C – ALONE, BACK, CRIB
Baby should sleep alone, in a safe crib or play yard, in the same room as the caregiver. Baby should always be put down to sleep on his/her BACK. The risk of SIDS is much higher when a baby sleeps on his/ her tummy or side.
Takeaways. Babies do best in a cool room (68–72˚F). A cooler environment helps prevent SIDS. Your baby's skin on the chest and stomach should feel warm and dry.
Going to bed too warm can cause mild side effects from poor sleep to a heat rash, but research has also linked overheating to an increased risk of sudden-infant-death syndrome (SIDS). For infants, a normal temperature is considered to be 97.5 degrees fahrenheit (36.4 degrees celsius).
