Achtung, Die Herdmanns Sind Zurück

Their antics are so memorable and funny, but I wonder if the author based them on real kids or created them from imagination. What inspired their personalities?

The Herdmanns' pranks made me laugh, but I also wondered if younger readers might find some parts a bit too wild. How do others think the tone balances fun and chaos?

The cozy, festive atmosphere really brought the story to life. Was this inspired by a specific place or tradition, or did the author create it from scratch?
