A two-year-old boy's been hit by a bus in Hamilton North on Monday morning.
The incident happened on Chatham Road just after 8am.
Three paramedic crews attended the scene to stabilize his condition and treat the boy for leg injuries.
He's been taken to the John Hunter Hospital in a serious condition.
NSW Ambulance Inspector Jim Duffy says the boy was conscious throughout.
“The leg injuries were severe, so paramedics stabilised the patient and tried to manage the pain," Mr Duffy said.
“This was a very challenging job to attend. I can’t stress enough the danger that motor vehicles pose to children – and the need for constant vigilance around roads.”
