A group of bystanders have rushed to lift a car off a young mother, trapped underneath after it crashed into a cafe in Newcastle.
The car reversed into a parked taxi before mounting a footpath, knocking over the woman and her six-month-old baby and then smashing into the Perkins Street cafe after midday on Friday, police say.
Witness Bennett Joy told Fairfax Media a man presumed to be the woman's partner called for help.
"You couldn't see (the mother) at all and the father was screaming 'that's my baby, that's my wife'," Mr Joy said.
"Someone said get a (car) jack and someone else just said `let's lift it'. We all just got together and lifted it to get her out."
The woman, believed to be in her 20s, was treated at the scene for head and leg injuries.
She was taken to John Hunter Hospital and remains in a serious but stable condition, while her baby was taken to hospital with possible head injuries.
The driver of the car, believed to be aged in his 70s, and the taxi driver were both uninjured but have been taken to hospital for mandatory blood and urine testing.
A fifth person was also taken to hospital, a NSW Ambulance spokeswoman told AAP.
