Sarah invites Caillou to the Christmas show at her school. Mommy sends out cards. The whole family chooses a tree and decorates it. Caillou gives away toys his longer uses and Rosie finds gifts for everyone. Daddy gives Caillou a special calendar to help him count the days left until Christmas. Every night Caillou opens a window and discovers how children around the world celebrate this holiday season and how different countries have different traditions. Caillou Happy Holidays! communicates great values: the importance of family, sharing, caring for others, patience, open-mindedness, and much more!
