Baby Ivy dies days after mum and brother killed in Menangle Park car crash

A baby girl has died in hospital two days after she was involved in a horror crash that killed her mother and older brother in south-west Sydney.

A baby girl has died in hospital two days after a horror car crash which killed her mother and brother.

Three-month-old Ivy Prahastono was miraculously freed from the wreckage of her family’s car after it collided with a cement truck at Menangle Park, south of Sydney, on Monday morning.

She was flown to The Children’s Hospital at Westmead in a critical condition where she died on Wednesday morning.

Katrina Prahastono, 34, was driving with her two children, baby Ivy and son Kai, 2, when the accident happened on the Hume Mty, about 30km from their Denham Court home.

Mrs Prahastono and Kai died at the scene.

Distraught relatives said her husband Ian was at work when police contacted him to say his wife and son had not survived the accident, and his critical baby daughter was being flown to hospital.

Mr Prahastono, an account manager for a marketing company, was on Tuesday by the baby’s bedside while struggling with the loss of his wife and son.

“We are all heartbroken ... Kat was a beloved mother, wife, sister, friend,” a family spokesperson said.

“Ivy is critically in need of care ... we ask everyone to say a prayer for her recovery.”

The extended family asked that Mr Prahastono also be kept in everyone’s thoughts as he navigates such an “enormous personal tragedy”.

NSW Police said the 48-year-old driver of the cement truck, who was not injured, was taken for mandatory blood and alcohol testing.

Witnesses said the family’s car appeared to be performing a U-turn through an emergency bay between the north and southbound lanes of the motorway when it was struck just before 11.30am.

The impact was so great, the car’s engine was found 100m along the road while the vehicle was crumpled against a guard rail.

NSW Ambulance chief superintendent Mark Gibbs credited the baby’s capsule with potentially saving her life.

“It shows how child restraints work in such tragic circumstances,” he said.

He said the scene was “challenging” for paramedics, dealing with two fatalities and a newborn trapped in the wreckage forup to an hour before she was intubated and flown to hospital.

Crash investigation specialists remained at the accident scene into the night, working to determine exactly how the accident happened.

It was the second shocking fatal accident in three days involving young children and their parents.

Father Lance Danks-Brown, 43, and his two children Kayden, 14, and Sharna, 11, all died on Saturday night when their dual cab utility hit a tree at Coutts Crossing near Grafton.

The trio was travelling on Kangaroo Creek Rd when the crash happened in pouring rain about 9.30pm.

A Go Fund Me account has been set up to support the Danks-Brown children’s mother with costs associated with their funeral.
