Sudden infant death syndrome, or SIDS, is the leading cause of death in babies beyond the first month of life. Although there is no cure for SIDS, researchers may be coming closer to figuring out what causes it..

According to Dr. Marc Patterson at the Mayo Clinic in Rochester, SIDS is the leading cause of death in infants beyond the first month of life, nationwide. Previous studies have proven that putting infants to sleep on their backs decreased the risk of SIDS. "There was a nationwide campaign to encourage parents to have their children sleep on their back," said Patterson.
