Caillou is a big boy now. When his sister Rosie goes to bed, he can stay up with Mommy and Daddy. However, when the games and stories are over, when his parents leave the room and close the door, Caillou feels very vulnerable by himself in the dark. Sleeping alone with the door closed is an important step toward growing up and feeling independent. With the help of his teddy, Caillou will prove to his parents that he really is a big boy! Developed with the guidance of a child psychologist, Caillou: Good Night! illustrates how Caillou's ability to overcome his fear of separation helps him gain more independence in small but important ways.
