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.
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. they were born prematurely or at a low birth weight.
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.
Abstract. Epidemiologic data suggest that SIDS is related to the sleep state, but exiguous literature has addressed infants who had been awake at the time of sudden catastrophic deterioration and subsequent death.
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 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.
Its exact cause remains a mystery, but a recent study in Pediatrics has revealed a possible risk factor. 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.
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.
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.
It is important to make sure that your baby is a comfortable temperature – not too hot or too cold. The chance of SIDS is higher in babies who get too hot. A room temperature of 16-20°C – with light bedding or a lightweight, well-fitting baby sleep bag– is comfortable and safe for sleeping babies.
SIDS peaks at 2-4 months, is more prevalent in the winter months and typically occurs in the early morning hours when most babies are asleep, suggesting that sleep may be part of the pathophysiological mechanism of 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 that are too cold will not exert the energy it takes to cry, and may be uninterested in feeding. Their energy is being consumed by trying to stay warm. A baby that is dangerously chilled will have cold hands and feet and even baby's chest will be cold under his or her clothes.
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.
Do not let your baby's head become covered. Babies whose heads are covered with bedding are at an increased risk of SIDS. To prevent your baby wriggling down under the covers, place them in the "feet to foot" position. This means their feet are at the end of the crib, cot or moses basket.
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.
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).
While having a baby sleep on mother's (or father's) chest whilst parents are awake has not been shown to be a risk, and such close contact is in fact beneficial, sleeping a baby on their front when unsupervised gives rise to a greatly increased risk of Sudden Infant Death Syndrome (SIDS) also known as cot death.
These decreases range from 40% in Argentina to 86% in France. The highest SIDS rates in 1990 (>2.0/1000 live births) were in Ireland, New Zealand, and Scotland. More recently, the highest SIDS rates (>0.5/1000 live births) are in New Zealand and the United States.
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.
CONCLUSIONS. This study shows that breastfeeding reduced the risk of sudden infant death syndrome by ∼50% at all ages throughout infancy. We recommend including the advice to breastfeed through 6 months of age in sudden infant death syndrome risk-reduction messages.
