Boy sells lemonade to pay for his own adoption

SPRINGFIELD, MO -- Tristan is a 9-year-old boy with an entrepreneurial spirit. The young man recently launched his own business selling lemonade and cookies.

For some, it's a rite of passage. But for Tristan, it's even more important.

Tristan is a foster child and he's hoping he can collect enough money to help pay for his own adoption.

"You're welcome and thank you for helping our adoption," he belts as a customer walks away.

Foster mom Donnie Davis says four years ago, Tristan came to live with her.

His mother, who was living a life of prostitution and drugs, left the then 5-year-old boy on the door step of a shelter on a 17-degree day.

"I was scared to death," Davis says, "If he was scared, if he was hurt, what was going on through his mind."

Today Tristan has a new life, and says he feels safe and loved.

"...because she's better, I know she's responsible, taking care of me, and I know she's going to be a great mother," Tristan says.

Now all they have to do is make it official.

"He's already a part of our family," Davis says. "In mine and my husband's hearts, that's our son."
