ANTIGO, Wis. (WSAW) -- The Schacht family is getting ready for the trip of a lifetime, after Make-A-Wish Foundation Wisconsin granted their terminally ill son's biggest wish.
There are a lot of reason 7-year-old Steven Schacht is one-in-a-million.
"We usually pop wheelies on or bikes," 8-year-old Aidan Schacht said of his younger brother.
If you ask Aidan, he'll tell you Steven is a one-in-a-million companion.
"We usually eat breakfast at the same time and play video games," he said.
And a one-in-a-million role model.
"He's brave and scared at the same time," Aidan described.
But, ask his doctors, and they'll say he has a one-in-a-million auto-immune deficiency.
"Well, he's always been pretty sick," Steven's mother, Christina Schacht recalled, saying Steven contracted pneumonia for the first time when he was 2-years-old.
"He wouldn't respond to any medication," she said. "It's like the medication would make him worse."
In 2014, Steven spent three weeks in the hospital, where his parents thought doctors might get closer to a cure.
"They had to cut out his left lower lobe of his lungs," she said was the solution after treatment still didn't work.
Schacht says doctors still don't know what's wrong, or how much time Steven has left.
"For some people there's a light at the end of the tunnel, but for others, like Steven, it's just hoping we've done everything we can do," she said.
For this family, that light comes in the form of a wish.
"I was ecstatic," she remembered, "because knowing that something good can come out of this process is fantastic."
Thanks to the Wisconsin Make-A-Wish Foundation, Steven and his family are headed to Walt Disney World in Florida next week.
"He wants to meet all the super heroes," Schact said. "And ride the Lego cars!" Steven added.
A one-in-a-million wish for a one-in-a-million family.
"Hopefully they find out what's going on, so they can cure it," Schact said.
Steven currently has pneumonia in his right lung, but doctors gave the family 'OK' for a week-long trip to Disney World.
