(A42 wip title: "I Can Help Daddy With Rosie") Mom leaves for a business meeting, so Caillou helps Dad with caring for Rosie. For example, she doesn't like cheese on her macaroni and she always has a little water in her apple juice. Caillou helps Dad look after Gilbert too. Rosie bumps her knee on a chair, so Caillou kisses it to make it better. Then the two play house together. Daddy lies Rosie down for a nap. Caillou gets bored and wants to play with her, so he feigns sneezing to wake her up. Daddy reprimands him for it, calling his bluff. At dinner, Rosie won't eat all of her food, so Caillou does the old "open wide for the plane" trick. Daddy gives Rosie a bath and she fusses until Caillou gives her a rubber duck. That night, Rosie cries when Daddy tries to make her go to bed. Caillou explains that Dad needs to read them a story. Dad has Caillou read the story. When Mom gets home, Dad's fell asleep, whereas Caillou and Rosie are wide awake.
