Ella was only four months old when doctors discovered tumours on her kidneys. After years of chemotherapy, dialysis and surgery, Ella received a life-saving kidney transplant, from a very special donor - her amazing mum Samantha. Ella had her surgery here a little over a year ago and it was a complete success.
Most of the life-saving equipment that was used to treat Ella - and all of the dialysis equipment that is used to make children like Ella better - was provided by donations and wonderful events like Trick or Treat.
And that's why Ella and her family are hoping that you along with your friends, families, school and creche buddies or work colleagues will join them in hosting a Trick or Treat party to help make sure that every sick child gets the same great care that helped save Ella's life.
"I'll never forget the first time I got to hold her after the operation. It's hard to put into words. It was just tears of joy." Samantha's Mum
