For Jonatan, children's books are the place where he can fuse written and spoken language into fun play. Without the red lines of the Spelling Dictionary or the condemning glances of linguists. He believes that the earlier children become acquainted with the intricacies of the Danish language, the sooner they can develop and explore the language. In this way, they can increase the competencies for school and educational life.

Most of the inspiration comes from his own home. With two boys aged 9 and 3, respectively, he gets all the questions for words and phrases that adults take for granted. But as for the linguistically uninitiated is completely crazy. It is an eternal source of smiles and conversation between Jonathan and his wife. At the same time, it is an inexhaustible source of ideas for book projects.

Jonathan's goal is to make children's books, which are not just the ones the children want to hear. It should also be the ones that the parents would rather read aloud to the children because the books also contain something for them.
