A mother accused of killing her 13-month-old girl with a stab wound to the throat called her husband and said: "I've done something to the baby," a Victorian court has heard.
Umal Sharif Abdurahman, 28, of Reservoir, appeared in the Melbourne Magistrates Court late Monday charged with one count of murder.
Detective senior constable Jennifer Booth said the accused, who appeared unrepresented, had a psychiatric illness and significant mental health issues.
Det Sen Const Booth said Abdurahman called the baby's father about 11am Monday and said: "I have done something to the baby".
He left work and on the way contacted his brother-in-law to check on his wife and kids.
When the brother-in-law arrived he found Abdurahman at the front of the house with her three remaining kids, aged two, three and four.
One of the children directed him inside the house, where he found the baby in a bedroom with what appeared to be a single knife wound in the throat, Det Sen Cons Booth said.
Emergency services were called and the infant was pronounced dead.
Abdurahman was declared unfit for interview by police.
The three surviving children were not injured.
The court heard it was Abdurahman's first time in custody.
Police told the court there have been nine reported family violence incidents between the accused and her husband since 2013.
Magistrate Robert Kumar adjourned the case until Tuesday and ordered Abdurahman be seen by a doctor.
