Sudden infant death syndrome, or SIDS, is a rare but devastating event in which an apparently healthy infant dies suddenly, unexpectedly, and unexplainedly. The exact cause of SIDS is unknown, but we do know that certain external stressors, such as becoming tangled in bedding, can increase the risk.
Without determining what actually causes SIDS, however, there is no hope of finding a cure. Check out this gallery to learn about SIDS and the race to find its cause and cure.
