Illinois -- Three years after the death of 2-year-old Dax Locke, his mother Julie is receiving letters and Christmas cards from all over the world.
"The response is phenomenal,” Julie Locke says. “We get so wrapped up in this materialistic thing about Christmas, but what it is truly about is helping others, and being with your family, and making those memories."
Julie Lock says memories are sometimes all we have of the ones we love.
Dax was diagnosed with leukemia one year before losing his battle with the disease.
Since then, a song and made-for-TV movie have told his story of sharing one last Christmas with his family
The Heart of Christmas DVD was released last month, and Julie says it is flying off the shelves in Central Illinois.
"We're really hoping that it pushes me to my goal. I would love to hear that news for Dax."
The goal is to raise $1.6 million dollars, enough to run the research hospital for a day.
Recently, Locke spoke with Jim Maloof, whom was with the Saint Jude Children's Research Hospital's founder Danny Thomas when the hospital opened.
Maloof is ill and gave Julie some advice at a time of year that is difficult on the Locke family.
"You need to get back up, and you need to keep going,” Maloof told Locke. Julie says he told her the same words his own mother once told him, “You are going to help those children."
Locke says she is honored just to be in the presence of Maloof and all of the people who work at the Saint Jude Children's Research Hospital.
"Saint Jude is amazing, and they know that,” Locke says. “They just give you the best care in the world. They do God's work better than anyone I've ever seen."
She says none of her efforts are possible without the people who have donated to the Dax Locke Foundation, helping tell the legacy of a child still spreading the true meaning of his favorite holiday.
