Stewart attended school until the seventh grade and then continued her education by correspondence. She has since completed high school.

Her whole family all worked behind the camera and Stewart thought she would become a writer/director, but never considered being an actor. "I never wanted to be the center of attention – I wasn't that 'I want to be famous, I want to be an actor' kid. I never sought out acting, but I always practiced my autograph because I love pens. I'd write my name on everything." Stewart's acting career began at the age of eight, after an agent saw her perform in her elementary school's Christmas play. After a year of auditioning, Stewart's first role was a small nonspeaking part in the Disney Channel original film The Thirteenth Year. Then, she had another part in the film The Flintstones in Viva Rock Vegas as the "ring toss girl". She subsequently appeared in the independent film The Safety of Objects, in which she played the tomboy daughter of a troubled single mother (Patricia Clarkson). Stewart also played a tomboy in the film Panic Room, playing the diabetic daughter of a divorced mother (Jodie Foster). She was nominated for a Young Artist Award for her performance.
