*Wach doch auf* is a German-language children’s picture book by Jan Jütte, represented here by the 1999 Carlsen Verlag hardcover edition. The title translates as “Wake up,” suggesting a story built around waking, reluctance, surprise, or the everyday rituals that begin a new day. The available metadata does not include a detailed plot summary, so the work is best described as a young-reader title from a German children’s publishing context rather than by a verified narrative outline. This record preserves the work as a single book entity, with the 1999 Carlsen edition serving as the known bibliographic representation.
