i have a thing on the fridge. it goes like this....

Daily:
dishwasher, clean sink and kitchen benches, sweep under dinning table, general tidy up in all rooms-just picking up crap, making bed etc. clean cat tray.

(i try to make sure kitchen is done after dinner unless the dishwasher got put on before dinner then the dishes get left till the morning, and il do it all before i do anything else so its out of the way.also put the laundry on first thing too. i normally run around when dd watches playschool at 3pm and do the tidy up and now dd is a bit older she is getting better and putting her toys away after herself)

Every other day:
clean stove and tiles behind stove, do laundry (wash/hang/bring in/fold/put away), clean toilets.sweep house

weekly:
wipe down kitchen cupboards,dust,clean highchair,vacume and mop (i never get round to mopping!) tidy dds play room,clean bathrooms,

Monthly:
clean windows,move sofas and chairs and clean under,vacume matresses,tidy garden,dust around lights/in corners etc

Now, im not saying i stick to it, but i do try. it really helps to have a list. and i probably end up doing laundry every day that there is four of us.
