Monday: Change and launder all the sheets (that's a lot of sheets!). Water the houseplants. Dust and vacuum the front of the house (sitting room, living room, sewing room, kitchen). Boys vacuum their own rooms, empty the wastebaskets, and wipe fingerprints from doors and mirrors.
Tuesday: Sort out the fridge, clean where necessary. Bake bread and other cooking projects. Scrub kitchen in detail--counters, light fixtures, appliances, pantry, etc.
Wednesday: Clean my own bathroom, dust and vacuum my room. Get groceries (and pizza for lunch!). Catch up the laundry room--clothesbaskets emptied, ironing caught up, and laundry room dusted and vacuumed. Quick vacuum of the front of the house. Bake a dessert for our Bible study group.
Thursday: The girls and I pick up their rooms and their toy room, vacuum those rooms, and clean their bathroom. Errands in town.
Friday: Vacuum the front of the house (again! It needs it all the time!). Dust and vacuum thoroughly the boys' rooms. Clean those two bathrooms.
That's it! In addition to what I've listed, my kids have various daily chores that include doing quick cleaning in each bathroom, dusting specific areas, etc. And of course I'm doing laundry every day, and I keep on top of the kitchen. This plan allows each part of the house to be attentively cleaned once a week, and kept adequately well the other six days. Sticking to a sensible plan pays endless dividends--the house is never a pit, I always know what to clean instead of wandering around aimlessly, and doing a little every day is good for both me and the house.
