People attending today's funeral of brave little 'Batman Ben' Farrell have been asked to wear bright colours to remember his love of fun.
Ben (5), from Finglas, Dublin, who was diagnosed with a rare form of cancer on Christmas Eve last year, was surrounded by his family when he died on Wednesday.
He was nicknamed 'Batman Ben' due to his love of superheroes.
"Our beautiful Ben has fought the hardest of battles; he was surrounded by love every day of his life," his family said after this week's death.
"He has done us proud every step of the way ... now we must do him proud.
"They say if you can leave this world a little better than you found it you have truly lived. In only five short years, he accomplished this."
Ben had a Stage IV Wilms tumour and faced 19 rounds of radiotherapy.
Doctors at Our Lady's Hospital for Sick Children in Crumlin in Dublin had said their options were running out, but his family hoped Ben could be saved by taking part in a clinical trial at a US hospital costing an estimated €260,000.
The clinical trials had shown promising results in laboratory tests.
The family arrived in the US four weeks ago after raising an estimated €192,000. But sadly Ben died before the treatment could begin.
In honour of Ben being a "ball of fun" his heartbroken parents, Valerie and Alan, are asking those who are attending his funeral to wear "bright colourful clothing" as he was always "full of smiles".
They are also asking that people donate to the cancer charity, The Gavin Glynn Foundation, instead of bringing flowers.
His funeral announcement reads: "Ben's memory will be cherished forever by his heart- broken parents, baby brother Jack, adoring grandparents, aunts, uncles, cousins extended family, neighbours and friends.
"Night night, sleep tight, our little bundle of joy."
Ben - who had counted the Dublin Senior Football team, actor Jonathan Rhys Meyers and singer Christy Dignam among his fans and supporters - is reposing at his home in Lanesborough, Finglas until this morning, with removal to the military chapel of Church of the Sacred Heart in Arbour Hill, Dublin for the funeral Mass.
He will then be cremated at Glasnevin Crematorium.
