Sudden Infant Death Syndrome (SIDS) is the sudden and unexpected death of an infant under one year of age in which an autopsy, scene investigation and review of the infant’s history does not show an explainable cause of death. Sometimes SIDS is referred to as “crib death”, however cribs do not cause SIDS. Rather, many infants who die of SIDS do so when they are sleeping and are found in their cribs.
The new term being used is SUID (Sudden and Unexpected Infant Death). This term is used to describe any sudden and unexpected death whether explained or unexplained that occurs during infancy and most often during sleep.1 Examples include SIDS, suffocation, strangulation, poisoning, infections, metabolic and cardiac problems, and cause unknown.
