He couldn't play in a normal treehouse, so Make-a-Wish made him one of his own.
7 year-old Hayden Trigg has used a wheelchair for his entire life.
Hayden is from Austin, Texas, and suffers severe complications from congenital skeletal and nervous system disorders, making muscle coordination and movement extremely difficult.
It's a big battle to fight.
But even though he's faced more adversity than most adults, Hayden is still a kid. He loves planes. And he loves trains.
After watching an episode of Discovery Channel's "Treehouse Masters," he fell in love with treehouses, too.
It didn't look like playing in a treehouse fort was something Hayden was ever going to be able to do, though.
That is, until the Make-a-Wish Foundation and its partners stepped in.
His family reached out to Make-a-Wish to see if there was any way they could help.
Last year, they found out that, amazingly, Hayden's wish was going to be granted: He was getting a treehouse.
“He spent months in the hospital last year — three months,” mother Adrienne Trigg told The Statesmen . “Everywhere we’d go, he’d tell people, ‘I’m getting a treehouse built for Make-A-Wish.’ It was something to look forward to and a distraction."
Two local companies, Austin Tree Houses and BioTrust Nutrition, also joined the effort to make a treehouse happen for Hayden, providing the funds and labor to create one seriously impressive structure.
Take a look at Hayden's amazing new hideaway:
On May 17, the treehouse was finally finished. And Hayden's entire first-grade class came by to help him break it in with an epic pizza party.
Pretty soon, the treehouse was swarmed with kids, including a beaming Hayden.
Rob Soluri, the owner of Austin Tree Houses, said the structure was a $50,000 project. He told Upworthy it features two stories, a 65-foot ramp for Hayden's wheelchair, posters of Hayden's beloved trains and planes on the wall, and a bucket and pulley for hauling toys up into the second-floor loft.
"It was the best day of his life," Hayden's mom told " Good Morning America ."
Even though the treehouse was built just for him, his mom says the long, wooden wheelchair ramp is still a struggle for Hayden.
Wheeling himself up to the house to play is a challenge. But it's a challenge he's tackled head-on as he continues physical therapy.
Cheers to Hayden for fighting for his right to be a kid, and to all the incredible heroes standing diligently in his corner.
