I do most house/child related things myself as DH works longer hours.
On my office days, I get in at 5.30. Dinner is always fast eg pasta (sauce made in oven) stir fry, steak and sweet potato fries with veg. I put the dinner on straight away so were eating by 6.15 latest.
While the dinner is cooking, I will also be starting DCs lunch for the next day, unload the dishwasher and light the fire.
By 6.30 I am washing pots and pans from dinner, everyone loads their own plate into the dishwasher. Kitchen is wiped down and a quick blast with the hoover if its very bad.
I'll fold washing off the airer.
By 7pm all jobs are done. I sit by the fire, play with Dc, help them organise shower or baths.
5.30 to 7 can be hectic, but its worth it to sit down at 7.
Dc go to bed at 8.30. I aim to be asleep at 10.30 and wake at 6.45.
As for everything else - while I'm waiting for the kettle to boil in the morning, I put away pots from the draining board, turn on the washing machine, finish DCs lunches and pack their bags.
Hoovering is done mainly on my wfh days. Mopping on a Sunday. Food shop delivered every Friday. Dinners that require us to follow a recipe are for Saturdays.
I wouldn't have energy to be doing housework at 9pm.
