After moving to Los Angeles, Hewitt appeared in more than twenty television commercials, including some for Mattel toys. Her first break came as a child actress on the Disney Channel variety show Kids Incorporated (1989–1991), which earned her, as a member of the cast, three Young Artist Award nominations. In 1992, she appeared in the live action video short Dance! Workout with Barbie (1992), which was released by Buena Vista, and obtained her first feature film role in the independent production Munchie, in which she played Andrea, the love interest of a bullied young boy. A year later, she had her first starring role in Little Miss Millions, as a wealthy nine-year old who runs away from her stepmother to find her real mother, and appeared as a choir member in Sister Act 2: Back in the Habit. Hewitt played Pierce Brosnan's daughter in a pilot for NBC called Running Wilde (1993), which featured Brosnan as a reporter for Auto World magazine, whose stories cover his own wild auto adventures, but the series was not picked up and the pilot never aired. Hewitt later had roles in several short-lived television series, such as Fox's Shaky Ground (1992–1993), ABC's The Byrds of Paradise (1994), and McKenna (1994–95).
