Count me in. DH and I run the business, but as he also works elsewhere, I do all the admin on top of my work. I have 2 DC, 1 at school, and 1 at home 6 days a week, leaving me about 5.5 hours child-free a week. I have good patches, then not so good patches. I kondo'd the whole house last year, and it has, for the most part, stayed organised. At least until we had our loft converted and a bunch of other work done.
On a good day, I get up before the DC, empty dishwasher, load washing machine, sort bags etc for school, put out clothes for the day, and make sure I get 5-10 minutes to have a coffee in silence! I tend to find if I can start the day well, tantrums, laundry mountains, and urgent client queries don't phase me as much.
My aim with the house is to have no area that cannot be tidied in 5 minutes. Most of the toys are away in bedrooms. We rotate a few bits around for downstairs, using expedit / drona boxes, so it can be thrown in and put out of sight. Separate dustpan and brush for counters and table tops only. Clutter boxes for everyone, if you leave something lying around, it goes in those, otherwise we end up drowning in a sea of random items. Laundry I only fold in the evening, on the sofa, watching netflix. I'll then put it away the next morning when I go round and air beds, open curtains etc.
When it works, it works well. House stays nice (well, nice for my slatternly standards!), work gets done without me stressing about the house, and we have time for park trips etc. When something goes wrong, the wheels fall off and it all goes to shit.
