We are trying something similar to Kellz...
Well, trying!
Charlotte loves to clean - wiping tables and her high chair and carries a baby wipe around with her half the day.
She loves to wipe up her own table and tends t throw the food on the floor if she has finished her dinner and wants to 'clear the table' iykwim. she likes to clear the coffee table too and the book shelf lol
So I think so far we have thought along the lines of she is trying to be clean, not make a mess. Very rarely she will throw things on the floor to get some attention. If we take her food away just as you see the signs she is going to throw it, and give her a baby wipe, she is content to sit for another 10 minutes trying to clean the table ... A bit like watching for sleep signs, we watch for throwing signs at diner time!

Hope that helps a little anyway...Let me know if you come up with something else too!!
