Sending sympathy. I'm not great at being organised and I know what you mean about getting out of the house to minimise the destruction kids cause when you're at home all day.
That said, there's plenty I leave for the next day and I'm never still going at 10pm! If things don't all get done in a day, so what? Give yourself a break.
FWIW, my suggestion... kids love to help - make the most of it while you can! There are lots of things you could be doing with the children with regard to tidying. The kids are old enough to put their toys away and there are lots of ways to make that into a game of itself (let's race / one finds all the cars, the other all the Lego/ one does all the blue toys, one does all the yellow toys/ one does hard toys, one does stuffed animals etc)
My 2yo has a toy hoover and will push this around while I do the actual hoovering so he feels like he is helping. Could you get something like that for yours?
Agree with the suggestions of batch cooking, but also think about simple meals your kids could help with. If I'm tired, I'll have egg on toast for tea. 2yo dons his chef hat and apron, puts the bread in the toaster, I'll crack the eggs, we both have a turn stirring, 2yo has a go at buttering the bread (which I then "finish off"), and he is proud as punch at being such a good chef. Not the most exciting meal, but it's fine for a midweek tea once in a while! Are there any other low key meals you wouldn't mind the kids helping with?
Most kids I know love sweeping or dusting or cleaning the windows, so give them a duster and put on some music and do it together. You might have to do it all again once they are in bed, but at least while they are doing it, they aren't upturning another box of toys over the floor. Or it might be something they can do while you cook to keep them occupied.
I also keep a supply of blank cards in the kitchen and if DC is getting underfoot, I get him to draw/make a card. Could you suggest they make a card for daddy/grandma/the neighbour etc while you cook? If your kitchen is big enough for a little table, they can do it in the kitchen which will still allow them to say mummymummymummy, but they will be more occupied and less underfoot.
Let the kids help with laundry (they can help separate darks and whites, they can set the dial, they can push the button). Never too young to learn!
Also agree with previous posts regarding getting a new tumble dryer. Also, do you have a dishwasher or are you washing up by hand? If you don't have a dishwasher, would getting one be a possibility?
Also agree with @endofthelinefinally with regard to toddler bedtime routine.
Good luck @disneybee, I hope you can find a better balance soon.
