Three years ago, we first met a boy from Seaton Sluice in Northumberland who needed surgery in America to help him walk on his own.
Callum Brown has cerebral palsy and had spent his life using walking aids. His goal of walking unaided required fifty thousand pounds of fundraising, a pioneering operation, followed by a year of intensive physiotherapy.
But now he's done it, and he has received a standing ovation from his classmates.
Callum joined in with his classmates at New Hartley First School as best he could.
But his legs were holding him back.
A career as a footballer was a far off dream. To even walk on his own, he needed revolutionary surgery in America.
It involving cutting nerve signals in the spine which were sending the wrong signals to his legs.
The operation cost £50,000, a target reached through the generosity of people across the North East.
He had the surgery last January. And four hours later he took his first delicate painful steps.
Difficult daily workouts have made his legs stronger.
Katie Oakes has two reports. In the first she charts Callum's progress.
Here's Katie's interview with Callum his mother, Sharon and the charity that has helped him.
