Abstract. A triple risk model for the sudden infant death syndrome (SIDS) as described by Filiano and Kinney involves the intersection of three risks: (1) a vulnerable infant, (2) a critical developmental period in homeostatic control, and (3) an exogenous stressor(s).
Prenatal/pregnancy factors:
Getting regular medical care beginning early in and continuing throughout pregnancy reduces the risk of SIDS. Smoking during pregnancy greatly increases baby's risk for SIDS. Drug and alcohol use during pregnancy increases baby's risk for SIDS.
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).
Stomach sleeping - This is probably the most significant risk factor, and sleeping on the stomach is associated with a higher incidence of SIDS.
Environmental stresses could include tobacco smoke, getting tangled in bedding, a minor illness or a breathing obstruction. There's also an association between sleeping with your baby on a sofa or chair and SIDS.
Vulnerability includes all intrinsic risk factors, such as gender, prematurity, genetic polymorphisms and prenatal exposure to harmful chemicals. Environment refers to extrinsic risk factors, for example sleeping position, bedding and sleep location.
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.
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.
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).
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. Keep soft bedding such as blankets, pillows, bumper pads, and soft toys out of your baby's sleep area.
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.
Does bottle feeding increase the risk of SIDS? It has been shown that partial or combination feeding (breast milk and formula) and exclusive breastfeeding have been associated with lower SIDS rates.
Unsafe sleep practices include infants sleeping on their tummies or sides or in places other than cribs/bassinets/play yards, such as adult beds, baby slings, car seats, couches or armchairs. Also unsafe is sleeping with pets, other children or adults, or with blankets or other bedding, crib bumpers, or stuffed toys.
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.
Babies can become wedged between a parent's body and the back of a couch or the arm of a chair and the weight of the adult's body can prevent them from breathing. Sleeping with your baby on a sofa also puts your baby at a greatly increased risk of Sudden Infant Death Syndrome.
Whenever you put your baby down to sleep, day or night, give them a safe place to sleep. Always put baby to sleep on their back. Baby should sleep in their own cot, in your room, for the first twelve months.
Infants (children under 1 year) had the highest rate of death in all jurisdictions in 2020, accounting for 59% of all child deaths in Australia. Rates of infant deaths from Sudden Infant Death Syndrome (SIDS) and undetermined causes ranged between 0.16 and 0.52 per 1,000 live births.
What are the symptoms? 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.
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.
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.
Very young babies who sleep too deeply for long periods of time are at greater risk for Sudden Infant Death Syndrome (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. Infants who are in danger of overheating feel hot to the touch.
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.
