The risk of SUDI including SIDS and fatal sleeping accidents is greatest at 2-4 months, although the risk is there for the first 12 months. Babies' sleep environments can increase their risk of SUDI including SIDS and fatal sleeping accidents.
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. Slightly more boys die of SIDS than girls.
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.
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.
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.
White noise reduces the risk of SIDS.
A relatively famous study (famous if you read a lot about baby sleep, so honestly you should be a little proud if you haven't heard of it) showed that babies had a significant reduction in the risk of SIDS if they had a fan in their room.
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.
Use a firm, flat (not at an angle or inclined) sleep surface, such as a mattress in a safety-approved crib, covered by a fitted sheet. Keep your baby's sleep area (for example, a crib or bassinet) in the same room where you sleep, ideally until your baby is at least 6 months old.
SIDS and SUDI are rare and the risk of your baby dying from it is very low. The rate of SIDS deaths has declined in Australia due to safe sleeping campaigns. In 2017, 6 babies in every 100,000 died of SIDS. Most deaths happen during the first 3 months of a baby's life.
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 usually occurs when a baby is asleep, although it can occasionally happen while they're awake. Parents can reduce the risk of SIDS by not smoking while pregnant or after the baby is born, and always placing the baby on their back when they sleep.
The potential factors that contribute to the occurrence of SIDS include inadequate prenatal care, low birth weight (<2499gr), premature infants, intrauterine growth delay, short interval between pregnancies and maternal substance use (tobacco, alcohol, opiates).
Oftentimes, babies who succumb to SIDS have had a “minor infection” in the days before death. Infants' immune systems are immature, and breast milk helps to provide necessary antibodies to fight infections such as RSV, which can contribute to inflammation and lead to SIDS. Breastfeeding promotes safer sleep.
Goodstein said, when babies sleep in the same room as their parents, the background sounds or stirrings prevent very deep sleep and that helps keeps the babies safe. Room sharing also makes breast-feeding easier, which is protective against SIDS.
SIDS is scary to think about, and of course, you want to take every possible precaution to protect your baby. Still, know that an infant's SIDS risk is very small. Today, only 33 in 100,000 babies are affected by SIDS, according to the latest data from the Centers for Disease Control and Prevention (CDC).
Deaths could occur more commonly at night in older infants because sleep is increasingly concentrated into the night. Prone sleep position could work through a thermal mechanism, so that the variables related to bedding and environmental temperature would be more important at night.
SIDS is not the same as suffocation and is not caused by suffocation. SIDS is not caused by vaccines, immunizations, or shots.
SIDS has no symptoms or warning signs. Babies don't seem to suffer or struggle. They don't cry. Minor breathing or stomach problems might occur in the weeks before SIDS occurs.
The Moro reflex is the cause of your newborn baby to sleep with his arms above his head. This reflex, commonly referred to as the “startle reflex”, disappears by 6 months of age. It occurs when light or noise startles your baby, even if the noise is not enough to fully wake the baby.
Your baby still remembers sleeping in your womb for nine months which is a snug and safe place. It's where your baby first listened to your heartbeat. So when napping in your arms or on your chest, that same reassuring sleep association is being triggered. Babies also like the warmth and closeness of being held.
How can I tell if baby is too hot or too cold? The easiest way to tell if your baby is too hot or too cold is by feeling the nape of the neck to see if it's sweaty or cold to the touch. When babies are too warm, they may have flushed cheeks and look like they're sweating. An overheated baby may also breathe rapidly.
Infants are sensitive to extremes in temperature and cannot regulate their body temperatures well. Studies have shown that multiple layers or heavy clothing, heavy blankets, and warm room temperatures increase SIDS risk.
The AAP recommends room sharing because it can decrease the risk of SIDS by as much as 50% and it's much safer than bed sharing. Room sharing will also make it easier for you to feed, comfort and watch your baby.
There's no treatment for sudden infant death syndrome, or SIDS . But there are ways to help your baby sleep safely. For the first year, always place your baby on his or her back to sleep. Use a firm mattress and avoid fluffy pads and blankets.
