One of the new rules we have this school year is that each of the four oldest children are responsible for preparing and cleaning up after their own breakfasts and lunches. I only serve the 3 youngest (and the 6 year old will probably graduate to self-sufficiency in the next few months) and the person scheduled to do that meal's dishes only has to do their own plus the two youngest children's. It's quite a bit less work for everyone which takes less time away from the school day.
It's making my life easier. Let me know if it does the same for you. Or, give me some ideas of what has made your life easier.
