Ollie was born with a rare metabolic disorder called urea cycle disorder (UCD). This type of UCD - called CPS1 - prevented his body from processing protein, which made the ammonia levels in his blood rise. He was put on a protein-restricted diet, where he was only allowed one gram of protein per kilo of body weight.
Hannah's eldest son, Kieran, sadly died from the same condition five years earlier, at the age of four.
After three months, Ollie had a liver transplant assessment at King's and was put on the transplant waiting list on Christmas Eve, 2015.
Ollie and his family were regularly seeing the team at King's as an outpatient and going in for clinic appointments. They got the call on what would have been Kieran's 10th birthday (on 23 August), saying there was a potential organ for Ollie, when he was just 11 months.
Ollie was given the green light to proceed with the surgery, which thankfully went well. Ollie recovered quickly and he was allowed to go home after 13 days.
Hannah said the care by the team at King's was amazing and they were really supportive. She also praised the play specialists who were always available to give the family games and toys for Ollie to keep him occupied.
It's now 10 years this year since OIlie received his transplant and he's doing very well – he's currently in his last year of primary school.
Ollie has yearly outpatients appointments at King's to have his bloods taken and his ultrasound.
Since 2018, Ollie has very proudly represented the King's Children's Transplant Team at the annual British Transplant Games.
This year, Ollie and Hannah cycled 120 miles over the month of July for his Transplant Games fund and in memory of his donor Miriam who gave Ollie his second chance at life.
Ollie's dad Mike also bravely took on a parachute jump to celebrate Ollie's 10th anniversary of his transplant.
