Exclusive: A father has described the alleged actions of a driver as “inexcusable” after his baby girl and mother-in-law were hit by a car in Sydney’s west earlier this week.

David Feng dropped off his daughter Olivia at daycare on Tuesday morning, not knowing that the next time he saw her she would be in a hospital bed.

Four-year-old Olivia and her grandmother Yumin Yang, 72, were allegedly hit by an 18-year-old man with a suspended license in Glenfield, throwing Olivia into a nearby tree and injuring her seriously grandma.

They had just gotten off the bus from kindergarten and were walking home when the unthinkable happened. 

Feng said he and his wife were in town when they received a call from paramedics.

“At first, I didn’t think it was real… I was very, very emotional,” Feng told 9News.

“I saw my little girl with blood on her face, but the moment she saw me, she actually smiled at me.”

Olivia has made a full recovery and returned home, meanwhile her grandmother Yang remains in a critical condition at Westmead Hospital.

She suffers from five broken ribs, a broken leg and head injuries. 

“(My mother-in-law) was unconscious at the time and a lot of doctors and nurses were around her,” Feng said.

“My little girl is doing very well, but I can tell that something is different from before.

“It was a shock, unbelievable, but also unforgivable.”

Yang had moved to Australia from China in February to help Feng take care of his wife and child.

The 18-year-old driver was released from hospital yesterday and has not yet been arrested or charged. 

Feng said he hopes charges will be laid soon.

“I didn’t know the young driver had caused the tragedy until I saw the news,” he said.

“We want to see the police do the right thing.” 

NSW Police said the investigation was ongoing and action was imminent.
