When I was at home with small children, my DH & I took the view that caring for the child was my job, and so we are both responsible for cleaning.

At our house, this meant DH cleaned floors, did laundry & ironed, and cleaned the shower. I did toilets, hand basins, bath, looked after kitchen, planned meals, organized groceries, most of cooking & cleanup. I also tended to do any dusting/tidying/sorting/picking up, and all the extra random jobs like fixing things, cleaning out cupboards or doing the fridge.

Now kids are a bit older & we both work, we get a cleaner once a fortnight. We still run around with a broom or vacuum & toilets, basins, etc still need to be done regularly, but because the house gets a thorough clean once a fortnight, we can see when something states getting untidy & just quickly do that one thing. Highly recommend it.
