Harry Maceachen and dad on liver transplant
Harry Maceachen ran amok in the BBC Breakfast studio in December 2015, while appearing on the programme to talk about his need for a life-saving liver transplant.
In March 2016, with no other donor available, his dad Simon volunteered to give Harry part of his.
Tim Muffett went back to visit the family to see how the recovery has been for both of them.
