The Caillou books make use of everyday situations to communicate what all toddlers feel so intensely in relation to themselves and the world around them.

Inspired by the work of renowned French psychoanalyst Dr. Françoise Dolto, Caillou books are designed to reflect the same range of emotions as those experienced by very young children.

It is Caillou's point of view, rather than reality as seen by parents, which is the foundation of each story.

Because Caillou is a human character, children easily identify with him. The simple illustrations and bright colors of Caillou's world naturally appeal to children and quickly capture their attention.

Caillou grows with his young audience: Caillou books are adapted to each age group from birth to age six. Each book leads to new discoveries and helps young children form connections to the world around them.

Caillou can also help parents better understand their child's psychological and emotional development, because the Caillou stories are based on real childhood emotions, giving parents insight into the emotions that children can't easily articulate.
