@Febreezefantastic I have really enjoyed your posts on this thread, and agreed with them.
I'm naturally a clean and tidy person - but I'm a single parent, a lot of stress related to that, 3 very very busy DC, and a busy f/t job. I can't afford a cleaner - but tbh, that's not even the issue as I am very particular about cleaning so I know I'd probably be a bit of a nightmare as a client. I also quite enjoy cleaning, once I have some time and energy.
The last couple of years in particular my house was really getting me down. It took me a while to realise the different factors - I felt like I was constantly tidying /cleaning each day, just to keep on top of everything but I still was needing to 'deep clean' at weekends and had no time.
I agree with you re: the comments on 'oh don't worry about your house being messy with small DC'. I have also realised that an organised and clean house improves my MH and my capacity to make good decisions and relax, even when I'm busy and stressed. It's more than just tidying / cleaning.
For me, I realised that I have to break the bigger jobs down into stages, that get done across a day / two days e.g. on my WFH days I might quickly clean the toilets in a break. Later that day, I might wash all the floors, and that night or the following morning, I'll do shower / sinks / bath. Each task is c15 mins, so 3 x 15 mins done separately = clean bathrooms. If I wait to have 45 minutes at one time to clean everything together, it's impossible and takes a bit longer as I switch between each task. Someone said, horrified, to me - but that must feel like you are always cleaning - well, yes, it does! But it's worth it to not let dirty bathrooms build up as a chore I can't get to.
I also have adopted the clean before it's too messy / dirty mantra - so another 15 minutes flying around the sitting room/hall with a duster mid week, before doing it again at the weekend, and hoovering every day. There's something about waiting until it really needs to be done that I find very stressful.
Finally, as everyone has said, I got properly into decluttering. I was one of those 'organised hoarders' e.g. each bedroom had shelves and shelves of books / toys / files etc, documents / kids' stuff was in boxes, neatly stacked. But it was still clutter, and I really realised that when I had to get a big job done, new boiler, and the workmen were in each room - but there was really no space - to move the stuff, for them to navigate.
I think OP if you are feeling unhappy with the state of the house, you are correct to deal with it. I think suggestions already made about a fixed time each morning or night - you and DP 15 mins at night, would have the basic cleaning up from the day sorted, and doing the same in the morning would get a daily wash on / out, quick tidy of rooms, beds, and bathrooms, and then the bigger tidying and cleaning would feel a lot more manageable.
