"Olaf and..." is a different kind of read-aloud book: It is designed not only to help with falling asleep but also to encourage listening, thinking along, and participating, fostering children's imagination and creativity with small puzzles and pictures to color. However, it also aims to challenge the reader: Shouldn't one know how many spines a hedgehog has or how fast a mole can move through its underground tunnels? In short, "Olaf and..." is meant to be enjoyable for both children and adults. Additionally, to ensure that other children can also benefit from Olaf, 2 EUR from each sold copy will be donated to the Mitmachkinder Foundation.
