If you are using the oven anyway for one thing, try to use up the space doing other stuff at the same time.
So if dinner is a roast, maybe bake some muffins/brownies for school lunches. Or when cooking a lasagna, roast some veggies to make a pasta sauce the following night. That sort of thing.
(Or bake some part baked bread with your cheese rarebit to make a simple supper with a glass of chilled wine!).
Use leftovers - we had fishcakes for dinner on Sunday, using a couple of tins of tuna and tin of sweetcorn, but also some of the mash made some seabass ones with leftover sea bass I had cooked and flaked and frozen a while back (I had expected an extra body for dinner who didn't show)...mmmm.
Leftover small amounts of meats like pork or beef or lamb can be frozen too, not just chicken, I use them thinly sliced in (mixed meat if necessary) Chinese dishes. Or leftover roast lamb reheated in leftover frozen gravy, along with leftover cauliflower cheese (or even fresh cauli and frozen sauce) and some freshly roasted potatoes is delish and easy midweek.
Leftover beef (roast or steak) can be used without freezing to make fab steak sandwiches for the following day.
When DD was small, I used to use reusable wipes on her bum, washing them in the machine with her nappies. I would keep them in a plastic sealed container which had some chamomile tea, little bit of witch hazel and a few drops of tea tree oil as a soaking "liquor", which seemed much more soothing on her skin than pre-packaged ones from the shops.
Now, I use a little sponge, that I wash out in the sink afterwards, for my facial wash/scrub, rather than wipes. It gets thrown in the machine with towels on occasion for a proper wash.
And we use a lot of face cloths in general, we don't buy wipes at all. They all just go in with the towels as well. And the j cloths.
