When Caleb's accident happened no one was sure if he'd make a full recovery.
On Thursday, he came to visit Channel 3, and showed us just how far he's come.
His dad is hoping Caleb's story will inspire others.
"His life has been an inspiration for me as his dad, and it's been an inspiration for our family," said Tim Brown You know ever since that boulder first struck him five years ago he's been an inspiration for so many people."
Timothy Brown remembers the day that changed his family forever. The Nashville family was camping at Fall Creek Falls when a boulder fell and hit two-year-old Caleb's head.
For months, it wasn't clear if Caleb would survive.
Channel 3 followed his journey as Caleb came out of a coma and later learned to walk.
