In an interview with "Variety", Baker said, "I wanted to executive produce because I wanted to see what it was like to build and fulfill a vision from the ground up, and since this was Disney Channel's first movie with an adult lead, I wanted that role to be protected and I wanted the movie to have my creative stamp on it." She also liked that she got to work on the Disney movie because it taps into her family unit fanbase. In 2016, she starred in the faith-based Christmas film, "Wish for Christmas".
