At least 30 babies have died of asphyxiation because they were placed in unsafe sleeping arrangements in the last five years, a coroner has found.
Another 19 babies who slept in an unsafe environment died in the same period, though their cause of death was not formally established.
Chief coroner Neil MacLean has released a recap of coronial findings into cases of Sudden Unexpected Death in Infancy (SUDI).
It shows there were 163 infant deaths attributed to SUDI since July 2007.
Unsafe sleeping, prone sleeping or sleeping with another person in the bed were highlighted as major preventable causes of death among infants.
