A woman has been charged with the murder of an eight-year-old boy on the Mornington Peninsula.
The 41-year-old was remanded overnight to appear before Melbourne Magistrates Court on Friday.
Homicide squad detectives attended a suburban address on Thursday afternoon following a call to Ambulance Victoria and subsequent discovery of the child.
The woman was taken into custody at the scene and a closed out-of-sessions hearing was held on Thursday night.
The pair's names and relationship to each other were not released.
