Sudden Infant Death Syndrome is the unexplained death of a seemingly healthy baby, usually during sleep. It's the leading cause of death for infants between 1 and 12 months. Following safe sleep guidelines like putting babies on their backs and keeping cribs clear of loose bedding cuts the risk significantly.
Example: The AAP recommends room-sharing without bed-sharing for the first 6 months to lower SIDS risk.
