A Melbourne grandmother who threw a clothes horse across the room, impaling her infant grandson's head, has avoided jail.
Victoria Sumner, 52, of Reservoir was on Monday handed a two-year suspended sentence for the April 2007 incident that left her grandson with a brain injury.
Sumner, furious after an argument with her youngest son, had retreated to a lounge room lit only by a television to let off steam on April 30 last year.
She did not know baby Tyrhys was in the room when she picked up the clothes horse and threw it.
The resulting injury caused part of Tyrhys' brain to protrude.
"This offence has had tragic consequences for the child ... who has an acquired brain injury," County Court Judge Christine Thornton said in sentencing.
Judge Thornton said Sumner suffered a major depressive illness and anxiety stemming from a series of events, including the murder of a son.
Sumner is a member of the Stolen Generation and was taken from her parents when she was 12 months old.
Sumner had pleaded guilty to one count of negligently causing serious injury.
