I have answered this already.
Yes SEN children. One diagnosed one under assessment. Higher rate daily and mobility. One NT. DH leaves home before DC are up, and returns (usually) after bed. I pull more weight with all the household stuff, because I appreciate how much more he earns and what it gives us as a family.
And actually the school run was a ball ache today. Going was fine. In out, done. 5 minutes. Home time? Nope. We took 15 mins to leave the grounds because of a tantrum over a piece of paper that had been folded the wrong way. Then we sat in the car and spoke about how we can get another piece of paper, which took about 10 further minutes to go from hysterical to "ok, we can just get another piece.". But it's not every day, at all. Neither is it for OP.
Anyway. OP doesn't work. The whole point of her working/not working is not the issue because she can't even accept there's enough hours in the day to have no children at home, no job, but do the laundry and lay out uniforms. It's the fact she calls it an impossible task to get the basic household chores done in 30hrs free time a week while her children are all in full time education setting.
As many people have pointed out, this impossible task is what most of us do outside of full time work hours, and the idea of having 30 child free hours a week, and no job to fulfill, is an inordinate amount of time to get everything done. Whereas OP keeps trying to insist that because she makes these things take all day, that she's doing the equivalent of full time work.
