Suzi Barrett is five years old and the younger sister of Buddy Barrett, the older sister of Marnie Barrett, the daughter of Natalie Barrett, and the stepdaughter of Franklin DeWitt. Her step-siblings are Lindsey, Ryan, Taylor, and Madeleine DeWitt. Suzi is a member of the Barrett/DeWitt Family. She makes her first appearance in Dawn and the Impossible Three.
Suzi is described as round-faced and pudgy with pigtails, curly brown hair, and a fat round tummy.
She is part of the Save the Planet class. She, Karen, and Andrew make "Think Green, My Kids Care" buttons. Their booth gets temporarily smashed in Dawn Saves the Planet.
She believes in Santa Claus although her brother, Buddy, mocks her for this. When she moved from one house to another when her mother married Franklin DeWitt, she was afraid Santa wouldn't be able to find her because she had moved. To solve this, she leaves a trail of cookie crumbs so Santa can find her new house.
She orders moondust through the mail. Suzi and Buddy perform "Mother's Helper" play during the traveling salesmen show. She ends up keeping the moondust instead of selling it with the rest of the stuff in Stacey's Choice.
Her favorite sitter is Dawn. In Dawn and the Impossible Three, she learned how to use the phone and call her even when she had nothing to say. She was upset about her parents divorce and didn't want to believe her dad wouldn't come back.
