Organisation and habit are the keys to my house being tidy and clean. Admittedly we have a 3 bed semi which isn't massive and am on mat leave with DS 10mo.
We have 2 of the massive Ikea storage units/bookcases which have 10 baskets in the bottom row for DS's toys, the random wires, paperwork. I sort out the paperwork once a month in the evening if it's not urgent.
I clean the bathroom when DS is having his bath - just flick round with the wipes, do the loo. Not every day, maybe every 3rd day unless we're having visitors/it needs it. Spray the shower door every morning when it's wet. Don't tidy during the day as pointless with 10mo whose main source of fun is pulling books off shelves and toys out of boxes. Once he's in bed, I do it. Try to wipe kitchen surfaces when they need it and always put dishes in the dishwasher immediately.
Luckily DS adores riding the vacuum cleaner so I just get on with it if it needs a quick zoom downstairs. Floor washing happens when he's napping as our family room, kitchen, hall and dining room have wooden floors. Front room rarely gets used, so might vacuum carpet when doing rest, but not always.
Laundry - and if it's full, dishwasher - on most nights. Hang out/up clothes in the morning. Don't iron anything. Sometimes piles of clothes in spare room, but try to put them away the day they are dry, don't always succeed.
Vacuum, dust everywhere at the weekend. Big jobs get done once a month at the weekend.
I used to have a very demanding job in professional services marketing that required me to be super organised as I was working on up to 20 projects at once, so I think I've shifted that mentality onto this new 'job' of looking after DS and the house & garden. Sometimes if we're out a lot or I'm feeling lazy, I don't do much and the floor, bathroom and kitchen look grotty/there's dust everywhere, but the very least I will do is stay on top of the laundry and tidy up every night.
