Mounting evidence suggests that some SIDS babies are born with *** brain abnormalities *** that make them vulnerable to sudden death during infancy. Studies of SIDS victims reveal that many SIDS infants have abnormalities in the "arcuate nucleus," a portion of the brain that is likely to be involved in controlling breathing and waking during sleep. Babies born with defects in other portions of the brain or body may also be more prone to a sudden death. These abnormalities may stem from prenatal exposure to a toxic substance, or lack of a vital compound in the prenatal environment, such as sufficient oxygen. Cigarette smoking during pregnancy, for example, can reduce the amount of oxygen the fetus receives.
#2 If there is a family history of this disorder or childhood death of unknown cause, genetic screening of the parents by a blood test can determine if they are carriers of this disorder. If one or both parents is found to be a carrier, the baby can be tested soon after birth.

SIDS is disorder. There is no questiona about that. It is part of Child Psychology, Abnormal Psychology, Developmental Psychology...
Anyway, thanks to all of you for your comments but I need translation not really an explanation.
