"As the writer of Harry Potter, I'm always nervous of committing myself to another children's book, but yes, the next thing I write will be for children," she told The Daily Telegraph.
"I have a lot of things on my laptop currently, including a couple of things for children - for a slightly younger age group than Harry Potter was aimed at - which are nearly done and will, I think, be the next thing I publish.
"I have run them by my children and they seem to like them which is always a good sign. I also have some ideas for another book for adults but it isn't too far on [in development]."
Rowling recently revealed that she is tempted to write a 'director's cut' of the Harry Potter novels.
