We have a bungalow, but inlaws rent apartment downstairs so our house is essentially one level.
I start in Kitchen every morning - give dd toys to play with in high chair or put her on play mat and do the kitchen - load dishwasher, clean counters/cupboards, sweep, etc.
I then grab laundry basket and tidy room to room throughout the day when it is convenient for DD and i and put ANYTHING that is not where it should be into the basket. At the end of the day I empty laundry basket and get things back where they should be.
This and a few loads of laundry is all I can really manage on a day to day basis... Anything else has to wait until DH is around to help.
It is driving me nuts though.
