Unlike many posters, I don't think OP is smug. She's just incapable of understanding/tone deaf.
I don't think she can compute (because she literally states "difficulty" in her posts) that laundry is not difficult. I'm not entirely sure why she thinks something that is a "two minute job" in her house is far from that in others. And that hanging round the house all day in order to move three loads from basket, to machine, to dryer, to drawer...being there at the right time to actually fit 3 washes a day in, is the nuisance.
As I said, I also have DTwins. And a teen. And myself and DH.
DTwins are pre school. Teen is in school all day. DH at work. I go round three laundry baskets and sort whites/darks/coloured/delicate. Then I'll take the whites, and set the wash off. I then need to be in the house to remove that from the machine 1.5hrs later, pop in the dryer, and get the load of darks in the machine. An hour later, the whites are dry, so they need folding and putting into 5 piles (me, DH, teen, twins, things which need proper ironing) which takes around ten minutes. I'll then go up and put those away, in three different rooms and on my way back down bring the coloured items and plonk in front of the machine which has about ten minutes left on the dark wash. Then the darks go into the dryer, the coloureds go in to the machine etc etc. Every other day is someone's towels wash, or a bedding wash too. So there's remaking however many beds to make time for too. Plus ad hoc items, blankets, dressing gowns, pe kit, table linen. Today was two sofa cushions, thanks to boy twin spilling a drink. Also, with DTwins being little, often there are grass stains/paint/random orange sauce stains that need a good pre wash treatment. Their coats get washed weekly too.
None, I repeat, none of this is difficult. Anyone can do it with their eyes shut. But to suggest it takes no time at all is frankly ridiculous. And I've done this day in, day out for years. I'm not slow at it. If folding a whole load from the dryer apparently takes two minutes, then it's to a very different standard than I would be happy with. It's just a bit stupid to suggest that a "mind shift change" is the issue.
Fewer children, older/less messy children, being in the house all day, other people being around/old enough to put their own things away or sort their own laundry, that's what would actually help. Funnily enough, these apply to OP...
