A mother has been charged and will face court in a bedside hearing after she allegedly attacked her three children as they slept, stabbing them multiple times in the family home.
The 47-year-old woman is under police guard in hospital on suspicion she was trying to kill the children â aged 10, 13 and 16 â on Monday.
She has been charged with three counts of cause wounding/grievous bodily harm with intent to murder and is due to appear in Parramatta Local Court via a bedside hearing on Tuesday.
The children were expected to survive their injuries but âtime will tellâ how the psychological scars heal, police said.
Their mother allegedly turned the knife on herself following the early morning stabbing.
âUntil we have an opportunity to speak to her, we wonât know what her intent was,â Detective Superintendent Naomi Moore said.
âBut weâre certainly taking it as a potential attempted murder.â
The father and the children â one of whom has paraplegia â were all in their bedrooms of the family home at Baulkham Hills during the attack, police said.

Forensic officers spent most of Monday at the scene following the attack in Sydneyâs north-west, where a childrenâs basketball hoop sat in the yard behind police tape.
One investigator was seen dusting the front door security screen for fingerprints, underneath a CCTV camera aimed at the doorstep.
Police said a âhouseholdâ knife had been seized inside the home.
The incident, which woke the father, was âcompletely unexpectedâ.
âUpon waking up to what I would believe to be a number of screams or yells, he has ⌠secured the weapon and heâs contacted police,â Moore said.
âThereâs certainly no domestic violence history reported to police ⌠thereâs no AVOs (restraining orders).
âThis is the first time police have responded to the house for any type of domestic situation.â
The womanâs behaviour had been described as âa little bit erraticâ in the days before the stabbings, Moore said.
A 10-year-old boy was stabbed twice, a 13-year-old girl three times, and their older sister, 16, had one stab wound and multiple lacerations, police said.
Their mother had three stab wounds to her abdomen, believed to be self-inflicted.
Paramedics treated all four before taking them to hospital.
The children were expected to recover from their injuries, Moore said.
âThey should make a full physical recovery. In terms of a psychological recovery, I guess time will tell what that means for them,â she said.
Footage of the scene showed one of the children being stretchered away with a pink teddy on their lap.
Moore said it was a tragic incident.
âAs sad as it is, we havenât dealt with this family before, and I only wish that maybe we hadâve, maybe we could have reached out and helped this family sooner,â she said.
