Coroner's Finding: Baby B

0y · Male·unexpected death in infancy whilst co-sleeping with an adult and older child

A 2-month-old infant died unexpectedly while co-sleeping with his mother and 5-year-old sister on a mattress in the lounge room. Autopsy revealed no specific cause; asphyxiation from unintentional overlay could not be excluded but was not definitively established. The death occurred in an unsafe sleeping environment contrary to established safe sleep guidelines. The coroner emphasised that sudden unexpected death in infancy remains a leading cause of child death in Australia, with co-sleeping identified as a significant risk factor. Key lesson: healthcare professionals and public health agencies must repeatedly reinforce safe sleep messages—infants should sleep alone, on their backs, in their own cots—as evidence shows current community messaging is inadequately penetrating.
