A third-grader in Missouri has been selling lemonade to help pay for his adoption.

Nine-year-old Tristan Jacobson sold $1 lemonades Friday in front of the home in Springfield he shares with Donnie and Jimmy Davis, who have been Tristan's kinship guardians since he was 5.

Donnie Davis told The Springfield News-Leader that the lemonade stand and a weekend yard sale raised $7,100 to assist with the adoption legal fees. A further $6,900 has been donated via "Tristan's Adoption Fund" on YouCaring.com.

She says "there's not enough words to say `thank you' to everyone."

Davis says she and her husband already consider Tristan their son. She says the adoption is "more for reassurance for him, knowing that he has his forever family and he has our name."
