"After bravely beating a massive brain tumour when he was only 5, he now only has a few months left to live."
The only way to help Kaden, who is in Auckland's Starship Hospital, was keeping him "pain free and comfortable" while everyone felt helpless.
"Everyone is asking what they can do. You feel utterly helpless.
"But there is something you can do. Please gift Kaden a small donation, so that his parents, Rachael and Stephen, can give him as many experiences as they can with the time they have left. Your small kindness can help to create a few moments of happiness for this grieving family.
"Thank you from the bottom of our hearts, for your generosity towards our family. Every little bit counts," Bowers wrote.
Monies raised would be used to cover living costs and the loss of their income while they stay with Kaden in hospital, and battle through his treatments.
