Quick Look: Sleep-Related Sudden Unexpected Infant Deaths

Sudden unexpected infant death (SUID) is a term used to describe the sudden and unexpected death of an infant less than 1 year old in which the cause of death is not immediately apparent. Approximately 3,500 infants die suddenly and unexpectedly each year in the US. From 2004 to 2019, fatality teams in 42 states reviewed 28,110 SUIDs that occurred while the infant was sleeping or in a sleep environment.

The American Academy of Pediatrics (AAP) has updated its policy recommendations for reducing infant deaths in the sleep environment. Key recommendations on breastfeeding, sleep surface, and sleep location are summarized in this Quick-Look.
