A hands-on picture book about falling asleep, with evening rituals, a lot of humor and poetic pictures. Today there was a flight lesson with Mama Eul and her 10 owl children. But when everyone flutters back into the tree in the evening ... there is suddenly a child too many. A small bat followed them home, and now the owl mom has to bring it home. It is past bedtime. Who will put the little owls to bed? The readers slip into the role of owl mom and are asked to participate. They actively help to put the owls to bed, with sleep rituals: search for soft toys, brush teeth, count, sing, sing, hum quietly.
