With Hannah at first it was a lot of following her around and making sure she cleaned up before she pulled something else out. It's a lot of work on our part at first because it seems like you have to be constantly following them around LOL So they don't get the self rewarding behaviours like Doberluv said.
When she would be playing with something and she would get up and start pulling something else out I would tell her that she has to clean up first and I would bring her back over to the mess and we would sit and clean it up together (and also usually sing the clean up song LOL).
she still needs to be reminded every now and then to put her things back where they belong LOL
