In the North Star series, three-year-old Caillou continues to learn about life. He is also beginning to take his first steps into the wider world in an effort to understand his environment. The North Star books, conceived with a child psychologist, encourage personal growth and confidence by teaching children about themselves, familiar situations, and the challenges they might encounter in their daily lives. Caillou's adventures help children become confident that they can handle new experiences. The clear illustrations and simple texts provide ideal tools for language acquisition while fostering interaction between parent and child.
