So many questions :lol:
I do nappies every second day. Sometimes I'll throw bibs in with them so they don't go mouldy waiting for regular washes. I do these at night & hang up in the morning.
Clothes - I separate into lights & darks. I usually do both on Thursday and darks only on Sunday. We seem to generate a lot more dark. I mix the whole family's clothes together.
Towels & Sheets - When I have enough for a full load, I'll do these. I usually do separate loads for sheets & towels depending on how many I have. I only do them on Sat/Sun.
I work Mon/Tues/Wed - so I usually avoid washing these days.
I'm a complete weirdo & try to hang my washing on the line in order. I fold as I take clothes off, so I like to have one line per family member & the fifth line for everything else with similar items together. It doesn't always fit right though so I try not to get too picky about it. I also like to match my pegs. DH tries to make me use different colour pegs sometimes & it annoys me. When he helps I don't bother hanging in order as he refuses to & I figure it's better if he helps than have me do it all just to have it done my way. Yes I'm stupid & OCD but I think it's harmless.
& I have a 7.5kg front loader. I definately wouldn't go any smaller.
