The popular PBS character Caillou is a precocious bald four-year-old who is occasionally as moody as a real toddler. This makes him appealing to children as they can relate to his realistic behavior, although some parents may feel that Caillou's actions might encourage such behavior in their children. This particular tape finds inquisitive Caillou learning about the changing seasons. Caillou videos are aimed at toddlers up to the age of five. ~ Perry Seibert, All Movie Guide
