SIDS can occur anytime during a baby's first year of life (it's extremely rare after 1 year of age). Although the causes of SIDS are still largely unknown, doctors do know that the risk of SIDS appears to peak between 2 and 4 months of age and decreases after 6 months.
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.
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.
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. Find out how to stop smoking.
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).
A pacifier might help reduce the risk of sudden infant death syndrome (SIDS). Sucking on a pacifier at nap time and bedtime might reduce the risk of SIDS . Pacifiers are disposable.
Other things that SIDS is not: SIDS is not the same as suffocation and is not caused by suffocation. SIDS is not caused by vaccines, immunizations, or shots. SIDS is not contagious.
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.
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.
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.
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.
Overheating may increase the risk of sudden infant death syndrome (SIDS) in babies one month to one year of age. Many experts recommend that the temperature in the room where a baby's sleeps be kept between 68–72°F (20–22.2°C).
Additional recommendations for SIDS risk reduction include human milk feeding; avoidance of exposure to nicotine, alcohol, marijuana, opioids, and illicit drugs; routine immunization; and use of a pacifier.
According to Evolutionary Parenting, Japan has significant lower rates of maternal smoking and alcohol consumption — and research has shown that maternal smoking has a direct relation to SIDS. Factors like these could have a direct influence on the lowered SIDS rate for Asian children.
Results: The majority of SIDS deaths (83%) occurred during night-time sleep, although this was often after midnight and at least four SIDS deaths occurred during every hour of the day.
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.
For safer co-sleeping: Keep pillows, sheets, blankets away from your baby or any other items that could obstruct your baby's breathing or cause them to overheat. A high proportion of infants who die as a result of SIDS are found with their head covered by loose bedding.
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.
It just so happens that there is one bundle of tricks known as the “5 S's.” Pediatrician Harvey Karp pioneered this method when he brought together five techniques that mothers have often used and organized them into this easy mnemonic: swaddle, side-stomach position, shush, swing, and suck.
Sucking on a pacifier requires forward positioning of the tongue, thus decreasing this risk of oropharyngeal obstruction. The influence of pacifier use on sleep position may also contribute to its apparent protective effect against SIDS.
Beginning at the age of 1, co-sleeping is generally considered safe. In fact, the older a child gets, the less risky it becomes, as they are more readily able to move, roll over, and free themselves from restraint. Co-sleeping with an infant under 12 months of age, on the other hand, is potentially dangerous.
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.
Extremely loud - 100 decibels. No more than 15 minutes of unprotected exposure is recommended. Dangerously loud - 110+ decibels. Regular exposure of more than one minute risks permanent hearing loss.
The organization says the practice puts babies at risk for sleep-related deaths, including sudden infant death syndrome, accidental suffocation and accidental strangulation.
