Ask a children's author: Andy Griffiths of the Treehouse series wants to hear your questions – video

In a new interview series from Australia, we're letting kids take control. If your child is a fan of Andy Griffiths' books, with a burning query for him, please post it in the comments section of this article – or email the question (or a video of it!) to by 4 May. We'll compile the best questions – and Griffiths' responses – in a video out the next week.
