We train our children to clear their own dishes from the table before they are excused. If they forget or refuse to clear their dishes- I just leave the dishes at their spot (I DON’T do it for them).
If a child refuses or forgets to clear their dishes, this is what I do:
1. I don't clear their place for them.
2. At the next meal, every cleared space has new clean dishes and new food.
3.When everyone comes to the table and the forgetful or rebellious child complains about their lack of clean dishes or new food, I simple tell them that I didn’t have any space to put their new dishes down.
4. Usually this is all it takes to remind them, and they jump up and put their dishes in the sink. Then I place their new place setting down.
My response to their not clearing their dishes doesn’t bring a punishment or a fight, just a calm natural consequence kind of reminder that if they don’t clear their dishes then there is no space for a new meal! The kids get that really fast and develop a habit to clear their own dishes.
