At 20 months old, Briscoe Van Hook wears a backpack not filled with toys, but medical equipment which keeps him alive.
Briscoe was born with a kidney condition called Multicystic Displasia.
At this point, Briscoe spends hours overnight on dialysis. He's unable to eat like a normal child so he's tube fed.
Doctors at Texas Children's Hospital explained he would need a kidney transplant and it would need to come from an adult. Briscoe's grandfather Kyle Van Hook volunteered his own kidney.
"Basically to me it's a no-brainer, it's either going to be a fire truck or a kidney for Christmas, right?" said Kyle Van Hook.
Kyle and Briscoe will undergo surgery on Wednesday.
