When we were small, my younger sister, Cheryl, had a set of four mechanical dolls. She called them the McCann Family. They were a thinly disguised version of the Davis family. Cheryl decided that she was “Tom McCann,” the boy doll. I think she liked the idea of being the spunky and adventurous child. At first Tom could stand on his own. Later he lost his balance all the time. Cheryl diagnosed Tom with Polio. She fitted him with crutches and braces just like hers. (Cheryl was born with spina bifida.)
