knowing which babies are more likely to fall victim to it. Babies that are high risk (premature, low birth weight) are often put on breathing monitors that have an alarm if the baby stops breathing. Perhaps all babies at the risk age of two to four months should be placed on these monitors. Having babies sleep on their backs does apparently help to lower the risk of SIDS, but that information is not necessarily well known.

Physical factors associated with SIDS include:
Brain abnormalities. Some infants are born with problems that make them more likely to die of SIDS. In many of these babies, the portion of the brain that controls breathing and arousal from sleep doesn't work properly.
Low birth weight. Premature birth or being part of a multiple birth increases the likelihood that a baby's brain hasn't matured completely, so he or she has less control over such automatic processes as breathing and heart rate.
Respiratory infection. Many infants who died of SIDS had recently had a cold, which may contribute to breathing problems.
Sleep environmental factors
The items in a baby's crib and his or her sleeping position can combine with a baby's physical problems to increase the risk of SIDS. Examples include:
Sleeping on the stomach or side. Babies who are placed on their stomachs or sides to sleep may have more difficulty breathing than those placed on their backs.
Sleeping on a soft surface. Lying face down on a fluffy comforter or a waterbed can block an infant's airway. Draping a blanket over a baby's head also is risky.
