Caillou does not like to be interrupted when he is playing. Especially not for meals! Nevertheless, Grandpa is clever. When he and Caillou turn into bears, suddenly Caillou is as hungry as a bear! Many parents worry about their child's lack of appetite and are concerned about their health. However, children's appetites are notoriously variable. It is important to respect their own internal rhythms without indulging their every whim.
