Police say one child remains in intensive care after suffering injuries in this morning's collision near Rhws Primary School in the Vale of Glamorgan.
At a police press conference this afternoon, journalists were told the five injured children are aged between five and ten years old.
Their conditions are 'changing throughout the day', police said, but none of the injuries are life-threatening.
The child most badly injured is in a 'serious but stable condition'.
Meanwhile two adult women will be operated on after suffering broken bones in the incident.
Police confirmed a driver is helping them with their enquiries but the incident is not being treated as suspicious.
They also praised school leaders and thanked members of the public who assisted at the scene.
