"Caillou was initially created as a baby of nine months. When it was time for him to get older, the addition of hair made him unrecognizable. So we decided that Caillou would never have any hair, and he went on to become popular as a little boy who is bald," the show's website says."Caillou’s baldness may make him different, but we hope it helps children understand that being different isn’t just okay, it’s normal."Is Caillou still on TV?Sadly, there are no longer new episodes of the show on TV. The series ran for five seasons, from September 1997 until October 2010. There have been 144 total new episodes of the series.However, you can fortunately still watch reruns of the show!

But there's a special meaning behind his unique name as well."Christine L’Heureux named the character to honor Françoise Dolto’s work and contribution," the site says."The word 'caillou' in French means pebble, which was used in a ritual created by Dr. Françoise Dolto. Reflecting her philosophy of respect for the child as a person, she asked children to give her pebbles as a symbolic payment for her consultations," the description continues. "The appropriateness of the name was confirmed by an incident that took place at the very beginning of the project. Christine knew she had made the right choice when she heard a neighbor calling her child, 'Kayou, time to come in.'" So interesting!Luckily for children who love this show, in addition to watching Caillou reruns, parents can also order dolls, and other toys related to the series as well as books. There are even printable paper activities for kids to complete and an app as well.
