I do -2 loads a day and then don't tumble dry. It's because we have leon in cloth and i have csp and cloth wipes for everyone, lots of kitchen cloths and towels and pads for the steam Mop, then we go swimming 1-2 days a week plus we all have gym/ dance and football kits. I have a few small tips but not sure if they make so much difference !.
Towels , quick dry then straight back on the radiator. Stops them staying damp and needing washing.
Messy activities are done naked (the kids I Mean )
Nappy free time a lot , trying to catch leon on the potty which saves a few nappies.
If it doesn't smell or its not marked don't wash it
That's it really
