I love some of these suggestions :)
Some of my routines:
-clean/tidy/sort stuff as I go. Rooms/beds aired then beds made. Cat litter scooped (from the one normal cat litter tray we have) as soon as we get up (and before bedtime). Washing up sorted straight away. Laundry wash as soon as there is enough for a load - then on clothes horse/outside line, dry buddy/tumble drier asap. It makes things quicker/easier rather than doing giant chores (or having a laundry mountain). Put stuff away/get stuff sorted right away (or as soon as humanely possible!).
-batch cook - every so often, I'll do an 8-12 portion recipe, divvy it into single portions, label it and freeze it. I normally have several different meals available in freezer. Saves a fortune and much easier for me (I work FT shift work) and for the kids (one is working shift work, having finished A levels in the summer; the other is at secondary). We can pick the meal we each want and either have for lunch or supper (DC have food flasks for bringing hot meals from home, and use these for school/work or day trips). Less food waste too. I'm going to have to do a big cook up of things today - we spent December running down stuff in the freezers to make room for Xmas food, and I have a load of veg to use up/sort :)
-lists of chores are on a fridge whiteboard - everyone knows what needs doing (so no excuses!!). I have a teen and a 12yr old.
-for Xmas, I save the Amazon gift bags (and tags). I re-use these each year to "wrap" the DC presents in (and for anyone who come to our place for Xmas and opens gifts from us under our tree). Saves me a HUGE amount of faff, there is less wasted paper and it doesn't take me long to get things "wrapped". I have bought a pad of stick-on gift labels, so a new label will just go over the old one. I use the gift bags for the DC birthday presents too. I only wrap (with real wrapping paper) stocking gifts, and gifts for people outside the house (if that makes sense!).
Gadgets for making life easier: Litter Robot for the cats; auto cat feeders (2/3 cats have a prescription food, one doesn't. The feeders are microchip-read); robovac (with mop) for upstairs and for downstairs (downstairs one hoovers/mops twice a day, upstairs one is once a day). Also things like air fryer or instant pot.
