I vac and mop the entire house every week, usually Wednesdays (DH flies in and out Thursdays, so this way it is all clean when he gets home ;0 and fresh done before leaves so DD isn't under my feet)

The shower gets clean when I am in it every couple of weeks, it is just a curtain, so no glass or anything, but when it was I would clean it every week.

Sheets also get changed every Wedneday or sooner if DD wets the bed, or ours lol Hers get changed twice a week on average.

Toilets get done every few days, DD brings home bugs from kinder all the time, so the door handles, lightswitches, fridge doors, pantry door knobs, toilets, taps and sinks all get disinfected at least twice a week. (Glen 20 rocks for this lol Takes about 3 mins to do the whole lot)

I am getting someone in once a month to do the windows inside and out and also clean the oven - thanks DH!

My must dos though are vacuuming the floors, which can be done up to 4 times a week depending on how bad they get, but I only mop the once.
The shower in the 'kids' bathroom barely gets used so it isn't cleaned anywhere near as often as our ensuite.
The one task that really POs me that I seem to put off is the stove. It drives me BONKERS having a dirty stove, but I HATE cleaning it, so DH does it when he is home, and I try my best not to make it dirty when he isn't!

Oh, Wednesday is my cleaning day because it is when DD is at kinder too, so I can put the music on, do it, get it done and only takes half a day to do EVERYTHING.
