I'm not dissimilar but we have a bigger house and a cleaner and just one adult child at home now. I like everything neat and tidy and do it as I go. We are always guest ready. Don't put it down, put it away.
I cannot get my head around the laundry a la the op though although I do note that they don't seem to have clean clothes every day which I find a bit mingy - and I have a clean nightie after three wears. Our bed is done every two weeks, as is dd's. We have a 7 or 8kg machine and I do a minimum of four or five loads per week. Usually two dark, one coloured and two whites. 5 x 7kg is 35 kg so I do not see how the op does 2 x 10kg.
6 towels, 1 king duvet and sheet, 6 pillow cases, 7 work shirts for dh, 1 pair casual trousers, 7 x socks and pants, cpl pj's, 5 dresses for me, pair trousers, couple of tops, 7 x undies, 2 nighties, dd will have a combination of trousers, tops, dresses, undies pj's and of course there are tea towels and cleaning cloths which go on a 90° bio wash which also cleans the machine. I wash about three/four loads on Saturday and Sunday and do a couple during the week. I put it away as I go along and the cleaner irons.
