Clean plates, messy table

We are trying to teach the girls to take over their plates or bowls after dinner. After dinner last night, E took her plate over to the sink. I thanked her and then M deciding that she was through eating her blueberry pancakes, decided to remove the last 4 pieces of pancake from her plate and put them on the table. She then climbed down from her chair and dropped her plate in the sink. She knows that we try to eat everything on our plate before taking them over to the sink and when she can't finish eating whatever, she dumps it on the table. She is very proud of herself for accomplishing this task and it always makes me smile to see her run over to the sink with her plate and see the food piled on the table where she was sitting.
