The three-year-old was born with a kidney disease where the organs are enlarged from fluid - this meant ultrasounds every two weeks for the first six months of Finley's life, followed by nuclear medicine tests, surgeries and hospital stays.

His mum, Belle Langridge, said the little boy's spirits never faltered.

"We're very open about what happened to Finn, he knows why the scars are there and what happened to his belly, that they put medicine in to give his kidneys a break," she said.

"He takes it with a smile on his face. He was in ICU, swollen as anything, tubes coming out everywhere, and he still has this cracker smile on his face."

In January this year, Miss Langridge said they were faced with a new hurdle.

"He started displaying signs of gastro, but it turns out it was a type of E. coli that releases a toxin into the body," she said.

"He went into acute renal failure and his blood couldn't carry enough oxygen around his body so he couldn't maintain kidney function and wasn't producing any urine."

Finley spent seven days hooked up to peritoneal dialysis, followed by a catheter put into the arteries in his heart.

"He was so small though so they would keep getting stuck and clogging, and he ended up with sepsis," Miss Langridge said.

"So it was back to dialysis then, but that was leaking and there was risk of infection, so we had to look at other options or see how he went without it.

"By some miracle, he produced about three millilitres of urine, and his kidneys started worked again."

But the fight is not over, with the risk of Finley's kidneys turning again a real possibility.

Miss Langridge said her family has participated in the Big Red Kidney Walk since 2017, raising money for Kidney Health Australia. This year, though, the walk was cancelled due to COVID-19.

"I didn't feel comfortable not doing anything to help raise money this year, so I decided to hold a raffle instead," she said.

"We've gotten a lot of community donations already from businesses and people, but always have room for more and will raffle those off as prizes to raise money."

From cleaning packages, plants and jewellery, to butcher's vouchers, pamper sessions and everything in between, the Wagga community have banded together to donate to the good cause.

Raffle tickets are being sold both through the The Lucky Finn Raffle Facebook page, as well as at 22 Nagle Street on Fridays.

So far, Miss Langridge has sold $250 worth of tickets while a colleague said they had sold $200 worth.

"I would love to be able to raise $2000, and what we've done so far has really shown what a great community Wagga is - there's so much support and now we can help an organisation that gives so much back to those in need," she said.
