Merlin, I totally hear you. My kids are 7 & 8 . people think they are twins.
i have had 6 kids here all day since 8am.. (what fun)
it was..
We keep the kitchen, lounge area clean, lego in the corner, decks can get hosed down once a week, vaccum / mop every week. Bathrooms are cleaned.
As long as the dishes are done, I am ok.
My kids fold the clothes, and put theirs all away. It doesn't take long to pick up toys and put back in their rooms.
My washing machine goes from 6am. Ironing takes 30 minutes per week. my kids love money, star charts not so much..
They also like to ride their motorbikes, if the folding is done..
