Six-year-old Caitlin can sing! 

In just her second time on stage, the talented first-grader belted out Rachel Platten's "Fight Song," a tune with special meaning for her. "I wanted to pick a song for my mom because she was going through chemo, and that song talks about being strong and fighting," she said. 

Caitlin's mother Nicole is battling stage 4 breast cancer. When Nicole heard her daughter sing, she says "It made me very happy, very proud of her."
