A three-year-old boy has become the smallest – and one of the youngest – recipients of a kidney transplant in Northern Ireland.

Olly Cartmill was just 13kg (29lbs) when he underwent the life-saving operation, receiving a live donation from his grandmother Michelle.

Olly was born with an extremely rare condition known as TTC21B.

His one-year-old sister Etta has the same condition and will require a transplant when she is older.

“We always knew Olly was sick,” said his mum Dionne.
