Brothers and best of friends: Ollie and Finley Cripps (Picture: SWNS)

A big brother has been hailed a ‘real-life superhero’ after volunteering to donate bone barrow to his three-year-old sibling.

Ollie Cripps, three, was diagnosed with acute myeloid leukaemia and desperately needed a transplant after relapsing, despite months of chemotherapy.

Luckily, brother Finley, five, was a match and immediately said he would undergo the gruelling surgery next month.

Mum Fiona, 26, from Sittingbourne, Kent, said: ‘We were very nervous to say the least, as they had informed us that there was a one in four chance that one of the siblings would be a match.

‘The relief was unreal. Ollie’s consultant and the doctors were astonished as it doesn’t happen.’

Brave Finley even asked his hairdresser to shave his hair off, like Ollie – but Fiona and dad Lee, 27, have asked him to raise £500 for Royal Marsden Hospital in London, first.

An online fundraising page was set up just before Christmas and within days he had smashed his target.

Fiona added: “We are so overwhelmed with everyone’s generosity. We think as a family it’s so important to support them as they are potentially saving our little boy’s life, because of this we want to be able to give something back.

‘We could easily just donate the money to the hospital. But we want to be able to see that we’ve made a difference to the families that use the play room and all the nurses there.’

The Go Fund Me campaign has nearly raised £1,000 for the Royal Marsden, where Ollie is being treated.
