Mother Who Poisoned Toddler Sentenced To At Least Three Years Jail

A Sydney mum who repeatedly poisoned her own baby, resulting in a battery of painful tests being undertaken on the young child, has been sentenced to a maximum six years jail with a non-parole period of three years.

The court heard the little boy was pumped with toxic levels of anticonvulsant medication by his mother -- often when he was supposed to be recovering in hospital, -- and the damage is likely permanent.

Judge David Arnott noted “the boy has endured painful procedures” and was rushed to hospital more than 30 times, allegedly suffering seizures.

Doctors investigated, with the child undergoing MRI’s, a lumbar puncture, electronic brain monitoring and ultrasounds.

Cannulas and nasal tubes were also inserted into his little body.

The court previously heard the young woman just wanted a “break” from life as a first-time mum.

The little boy was lucky to survive  -- and sadly may never recover -- with the level of brain damage and psychological damage still unknown.

Up until recently, he didn't even have teeth.

The woman, who can't be identified for legal reasons, regularly updated a Facebook page with photos of the sick child in hospital, in which she detailed her son's medical problems.

Police began investigating at the beginning of 2018 after the 18-month-old boy arrived at the Sydney Children's Hospital suffering from a serious overdose.

When police arrested the mother in June last year, the little boy was on death's door.

The 22-year-old mum had been poisoning her own son for weeks with the medication Tegretol, which is mainly used to treat epilepsy and neuropathic pain.

When investigators asked what the woman what she wanted to do, she responded: "a break I guess, and no one would let me."

"He wouldn’t be out of my sight, he would be attached to my hip. When he was asleep out of sight it was easier to get things done.”

The mother’s defence lawyer told her sentencing hearing last month that she is mentally ill and “it was a way to get attention from medical staff.”

“What drove her was her borderline personality disorder and Munchausen syndrome by proxy (MSBP).”

The young mum faced a maximum 10 years jail, but with time already served will be eligible for parole in 2021.

The boy is still recovering, with the true impact of the abuse unlikely to be known until he's older.
