OKLAHOMA CITY, OKLAHOMA -- It's Art Day in the Jimmy Everest Center at Children's Hospital.
No one is here for treatment.
Instead, these kids, who've all battled cancer, or who are still battling the disease, get to draw or paint something.
"This is a great event," says Linda Webb. "They treat the kids like royalty."
Kylee Johnson is here too.
She's a survivor, several months removed from her last chemotherapy shot.
Her parents Mariah and Jesse are still scared to breathe about their eldest daughter.
Of her original diagnosis, Jesse recalls, "It hit us all at once. It was near her birthday. It was close to Christmas time."
But they know they're part of a family of parents who know the feeling.
"It really felt like we had an ally," says Mariah.
Allison Webb would have been at Art Day if she could.
Her mom Linda, dad Scott, and big brother Logan all agree that art was definitely her thing.
"Painting," echo both Linda and Scott. "She loved to paint. She was very artistic. She would have loved this event."
Doctors diagnosed Allison at the age of 2 with the same type of cancer as Kylee.
The disease took Ally's life in 2003.
Through tears, Linda recalls, "Every day we spent caring for her and making sure she had what she needed, it was such a focus that I realized after she was gone that I had run out of things to do for her."
But the Webbs did something other than grieve.
They started a charity called Ally's House in her memory.
Scott Webb says, "Ally's House was a way we could keep her alive, and her legacy alive."
They designed it to offset the unexpected costs incurred by Oklahoma families with children in cancer treatment.
Quietly, over the past 13 years, Ally's House directed their donations to a thousand families.
They actually counted.
Kylee's family was number 1,000.
"We're really happy that you're our thousandth patient," says Linda to Kylee in a small ceremony to mark the event.
In a battle for their lives, these children, Kylee included, don't really know much about the financial battles their parents face in caring for them.
Part of Ally's legacy is that they don't have to.
