Two boys under 10 are among four pedestrians hit by vehicles in less than an hour during Sydney's morning peak hour, prompting NSW Ambulance to urge drivers to take greater care.

A five-year-old boy suffered head and leg injuries when a car hit him in Bankstown, in the city's southwest, at 8.15am on Monday.

He's been taken to Westmead Children's Hospital in a serious but stable condition, while his 30-year-old mother who was also hit has abdominal injuries and is at Westmead Hospital in a stable condition.

At 8.40am, a woman in her 50s was hit by a truck in the CBD and has been taken to St Vincent's Hospital in a stable condition.

Just after 9am, paramedics were called to Artarmon in the city's north to treat an eight-year-old boy who was hit by a vehicle on Broughton Road.

He sustained abrasions to his legs and was taken to Royal North Shore Hospital, a NSW Ambulance spokesman said.
