Brisbane Grandmother Charged With Attempted Murder After Four-Month-Old Baby Slashed With Cleaver

The baby boy is in intensive care.

A Brisbane grandmother accused of trying to murder her grandson by slashing his face with a large cleaver will undergo mental health assessments, while the four-month-old remains in intensive care.

The infant was found with facial injuries at a home in The Gap on Tuesday morning and was taken to Lady Cilento Children's Hospital, where he underwent emergency surgery.

He is in a serious but stable condition, with his mother by his side.

His 64-year-old grandmother briefly appeared in Brisbane Magistrates Court on Wednesday morning facing a single charge of attempted murder.

She sat motionless as her matter was mentioned.

The woman's lawyer, Glen Cranny, did not apply for bail on her behalf.

"There's some days needed to allow for some assessments to be conducted," he told the court, confirming outside they were to do with her mental health.

The child and his mother had been visiting from Sydney at the time of the alleged attack.

The mother was asleep and was alerted by her child's cries.

Police said paramedics and police who were called to the home first were visibly shaken and upset on encountering the traumatic scene.

"It was distressing to see such injuries to such a small child," Inspector Daniel Bragg said on Tuesday.

"This is the worst-case scenario.

"We deal in trauma, we're used to trauma. But probably the most affecting job you can go to is one involving a child."

The woman is not required to appear when her matter returns to court next Wednesday.
