I try to do a load of washing as soon as there is enough laundry to do a full load (if that makes sense?). I tend to get up early anyway, so laundry put in to wash first thing: in summer, it's then hung out before I go to work, in winter we use the tumble drier or hang onto hangers and left to dry in the bathroom. If I shake stuff out and then dry/hang straight away, there's no need to iron. Bedlinen we fold and then put in a pillow case (I think I learned this trick from here a few years back).
In the evenings, I fix packed lunches ready for next day (either making sandwiches or putting together the other bits for the lunchboxes). I've bought the kids a Thermos food flask each - this means they can have reheated leftovers for hot school lunch the next day (I heat this up in the mornings and the flask keeps the food really hot for when they have lunch). i.e. get shit ready so you have less faff in the morning.
I clean the kitchen, bathroom/WC and mop floors before I go to bed. I got a robovac last year and that's been amazing too: it has a daily schedule. This is v useful with 2DC and 3 cats! The mop I have is an electric spinny mop thing by Bissell, which I got on the last Black Friday. If I need to scrub the floor tiles, I add the green scourer stuff to the bottom of the mop pads. House is tiny, one bathroom only, so this isn't as epic as it sounds.
Wash shower/bath after each use (DC know to do this too). After bath/shower, spray tiles and wipe down.
Wash up/stack dishwasher as you go along. XH used to leave things to accumulate (laundry, dishes etc) and wouldn't think about cleaning/laundry/washing up until things were a state (and we'd run out of clothes/dishes etc).
Delegate housework - my DC know that they have to help! Our house is a v small one, so stuff needs to be put away/laundry folded and sorted etc straight away, otherwise the place looks a worse mess than it already looks!!
Four week menu plan (I have a wipe clean board thing on my fridge. The DC and I decide between us what evening meals we will have), then we can plan shopping, batch cook, use up stuff etc. I'm on my 4th week of doing this and it has saved me a fortune so far (no dialling for a takeaway when I don't have a clue what to make), and there's a shit load less "mental load" thinking on what the hell to cook.
I buy bulbs of garlic, root ginger and onions, then prep and freeze them in batches: peel garlic and put cloves in freezer bag; peel ginger, slice it and freeze; peel onions, slice/chop (I throw them in a food processor) and freeze.
Generic cards for birthdays/Xmas etc, plus basic wrapping paper.
I'm a SP working FT, so really have to be on top of stuff.
