Twenty-two-month-old Harriet and her dad Rory share a very special bond.
He saved her life by donating 20 per cent of his liver - the size of a soft drinks can - in operations which took place simultaneously at Birmingham Children's and the Queen Elizabeth Hospitals.
"She's full of smiles, she's walking and exploring things and she comes out with new words every day," said Rory, 34, a farmer near Whitchurch in Shropshire.
