The Organised Mum Method (TOMM) inspired my laundry system. Complete load of laundry EVERY day. That way it never builds up, never becomes overwhelming, never end up with a massive pile of clean laundry covering the spare bed and thus being used as bedding by our mucky hair-shedding cats.
Every night: load the machine with everything that isn't white and set it on a timer to finish when I get up in the morning. Put away everything that was washed earlier that day, if it's dry (leave until morning if not).
Every morning: Get the wet laundry out and put on overdoor airer. Put away anything from yesterday that wasn't dealt with last night because it wasn't quite dry.
Every Saturday: Normal daily wash, plus a separate whites wash for school shirts and DH's white t-shirts. (I basically don't own anything white myself, can't be trusted not to spill curry on it.)
Every Sunday: Normal daily wash, plus a separate towel and cloth wash at 60 degrees with no fabric conditioner - every towel in the house, plus the cleaning cloths.
Bedding gets done on whatever day it needs to be changed, immediately upon being removed from the bed. All double beds, so all a single load each. We have super cosy polyester bedding (sounds yuck, but it's heavenly) so it dries pretty fast draped over the bannister and can be put away within 24 hours.
And I do a special 'pants wash' every few days during my period, because I have those special period knickers that you rinse out immediately after use, store in a wet bag or box and then wash on gentle with no fabric conditioner and line dry.
I have to stay regimented with laundry or (due to executive functioning difficulties) I get utterly overwhelmed and it all falls apart. Also one child has sensory issues and gets very attached to certain items of clothing; with my system nothing gets buried in the laundry basket so as long as she has two tops and two pairs of leggings that she likes, they get worn and washed on rotation and she's always got one of her favourites ready to wear.
