Agree with lots of the minimalism above. Lots of great advice. My two penneth:
NEVER iron - I don't buy clothes that need it, didn't own an iron til i was >30; if anyone in the family wants pressed shirts, they can do them themselves. It's a personal preference IMHO. I might be lucky that DD is in primary so in stay-pressd pinnies and skirts and horrid polo shirts - but when she's in shirts I'll go poly-cotton not cotton, and she can iron if she wants them pristine. I have plenty of work clothes that are smart but don't require ironing. DP buys shirts that are checked, so noone sees the creases!
Washing on a short economy cycle so it's out and drying the same night it goes in the machine.
Dirty house. (Clean loo, clean kitchen surfaces, clean sink/bath. Filthy floors).
Over-cook most of the time (often by accident) so we have freezer portions in double-adult and kid-size of chilli, bolognese, dhal etc.
A repertoire of easy meals (spaghetti Bol, chilli, Dahl, chakchouka, couscous and veg, bean stew, sausage and mash) and a lot of non-perishables (tinned beans, couscous, pasta etc) and frozen veg (peas obvs and sweetcorn and baby broad beans a boon!) so you can always do something from scratch dead quick sans inspiration. Pasta peas and Parmesan is a winner here. Takes as long as the pasta takes to cook.
Haven't been doing packed lunches long enough to need to but will def get to making batches of sarnies or rolls and freezing them when I'm fed up.
All grocery shopping is online - snatched minutes at work when I remember items to add to basket, and in the evenings in front of the tv.
And the DC must help out with chores - we're all part of the family, we all want to have a nice time, so we all have to help out. Otherwise mummy's a drudge, grumpy and no-one has fun.
Good luck!
