I think it’s really sanctimonious if I say ‘I do it and it’s fine’ so forgive me, but I do find it fine but it took a while to get into the right stride. I work FT, sometimes with travel days, DH works away so juggling the 2 DC plus FT work, house and anything else is 100% me Mon-fri. I have no family nearby. I love my sleep too.
I get up at, take yesterdays washing off the airer and put it in the dryer on a 5 min timer to finish. In that 5 mins I take the washing out of the washer which I’ve put in on a timer overnight to finish and 7 and put it on the airer. I repeat this every night Mon-Fri alternative whites, darks, 2 bedding and one towels. robot hoover is timed to come on just after we leave so downstairs is always reasonably clean floor wise.
after that I call the DCs down, toast, tea, fish something out of the feeezer and put it in the slow cooker, wipe the sides and we all go up and dress and wash. We all shower and baths in the evenings.
8am on the dot we leave, I drop them at 8.15 and get to work 8.45. I collect them at 5, home at 5.15. They do homework (when younger they’d sit in the kitchen and read to me/younger than that I had toys in the kitchen, while I repack lunches for 3 of us, make any accompaniments for slow cooker food (ie rice or pasta or whatever) and we eat together at 6. Then we are generally all upstairs. We are out of supervised baths now but we did sharing baths when little, now one showers while the other plays or whatever then they swap. We then generally sit down as a family from 7.30-bedtimes. We might just watch tv but sometimes play a game or do a puzzle. I go up when the eldest goes up at 9, have my own shower, I do still read with them and find time for a bit of 1-2-1 chatting. I then pop back down and unload the dishwasher, put the washing in on a timer, ready to have the morning routine.
it’s been loosely the same since they were pre-school age, just tweaks to make it age necessary. Doing the washing in the week really helps. And at the weekend we don’t have anywhere near the same routine - which marks the weekend well and we all relax more.
maybe being so fixed won’t work for you, but for me it’s better than feeling overwhelmed and having no time for me - once they are in bed I get an hour to read, watch something, knit a bit.
