Doris is the mother of Caillou and Rosie. She usually doesn't talk much but she is along with Boris grounding Caillou. She has a bad habit of making weird noises around someone attractive, but oddly enough, she doesn't do it around Boris. She is also known to be very overprotective because in Caillou goes on trial part 1, she is invading Caillou's personal space when talking to Toyota. She is very smart because she finds strategies to ground Caillou for his behavior. She stands up to herself very well because if someone tries to hit on her or hit on Boris, she can get very nasty, she also protects the whole family using her words and her strength.
