If flylady is too much, make your own system. Give yourself a tour of the house. Decide what needs doing daily (emptying nappy bins, laundry, making beds etc), weekly (cleaning loos, changing beds, quick hoover etc) and what you can get away with doing monthly (proper hoover moving stuff, proper dust, etc). Sort your house into 4 'zones' that you can rotate through each week for the monthly chores (I've got boys bedrooms & main bathroom, our bedroom hall and downstairs loo, lounge study and kitchen dining as my four zones). Have times of day that you do stuff so you don't even think about it - it becomes automatic.
So, for example: in the morning I don't come downstairs until all the beds are made, toys tidied up in the boys bedrooms, nappy bin empty. I take down a load of laundry with me. While dh feeds the kids breakfast I quickly sort out whatever paperwork dumping ground I currently have or sort through emails.
At lunchtime, I make sure the kitchen is cleared up after lunch then do a quick whip round on whatever my weekly chore is for that day while kids are fed and happy - one distracted by telly, the other in bed for a nap (loos on Monday for me - oh joy).
After dinner, I make sure the kitchen is cleaned up again, do a quick whip round on whatever my monthly chore is (my zone is my bedroom this week) while dh picks up all the toys and starts getting the kids ready for bed.
When I go upstairs to bed I make sure that downstairs is all tidy, the kitchen bin is emptied and dishwasher is on.
Surprisingly, it takes much less time than all that writing allows. My house isn't immaculate, but it's passable most of the time
