What is SIDS?
SIDS stands for "Sudden Infant Death Syndrome," and is the sudden, unexplained death of a baby younger than 1 year of age that doesn't have a known cause even after a complete investigation. This investigation includes performing a complete autopsy, examining the death scene, and reviewing the clinical history.
When a baby dies, health care providers, law enforcement personnel, and communities try to find out why. They ask questions, examine the baby, gather information, and run tests. If they can't find a cause for the death, and if the baby was younger than 1 year old, the medical examiner or coroner may call the death SIDS.
