Who Are The Main Characters In The Small Wonder Book?

I recently dived into 'Small Wonder' and was struck by how the characters play off each other. Vicki, the robot girl, is the heart of the story—this uncanny valley kid who looks human but acts like a walking computer. The Lawrences, her "family," are a perfect sitcom setup: Ted, the engineer dad who built her, is equal parts proud creator and panicked parent. Joan, the mom, tries to keep things normal while babysitting a robot. Jamie, their real kid, steals scenes with his mix of sibling rivalry and protectiveness toward Vicki. Then there's Harriet, the nosy neighbor who's always sniffing around for secrets, adding that classic '80s sitcom tension. The dynamic works because each character reacts to Vicki differently—some see her as a daughter, others as a science project, and Harriet as a threat to the neighborhood.
What fascinates me is how Vicki's existence forces the others to question what makes someone human. Ted tinkers with her programming like she's a gadget, but Joan scolds him when he treats her like one. Jamie's the bridge—he knows she's not his sister, but he defends her anyway. The show's charm comes from these contradictions. Even Harriet, the antagonist, isn't entirely wrong—Vicki *is* unnatural, and that discomfort drives the comedy. It's a clever twist on family sitcom tropes, where the "child" isn't just mischievous but literally programmed to malfunction.
