== Trivia ==

• In "What's Ringette", it's revealed that she used to play ringette and that she was the leader of her team in High School.
• Unlike Grandma and Grandpa (from Boris's side of the family), Doris's parents are never seen in the entire series. It's known that she has a younger cousin named Bella, who was mentioned in "Caillou Watches Rosie".
• Her name is listed as Doris on the Caillou website, but she is referred to as "Mommy" through the books and TV show.
• Her favorite color is red, the color of her shirt.
• It's implied she and Boris were high school sweethearts or at least have known one another since high school (maybe even longer).

They both will make a mention of the other's days in high school. In A House In The Sky, Doris asks Boris if he remembers Carol 'from high school'.
