Sorting laundry, as opposed to bunging it all in one wash together, regardless (yes I know there are a bunch of MNers who do this, I'm not one of them and I prefer my clothes to survive the laundry process)
How to change a vacuum cleaner bag - he had the miele whining with pain, it was so full, he didn't notice the red warning or understand that the bag isn't magically self-emptying
How to pull curtains - seems to bypass DH's brain completely
How to make a bed properly and change linens
How to hang laundry so it dries with minimal creasing and therefore no need for ironing
How to clean the bathroom - noticing when the loo is in need of bleach etc., how to find the bleach and cleaning agents etc.
that's just a few off the top of my head. :)
Teaching DSs how to look for their own things as opposed to doing it for them every time they fail to find it the first glance will be a big one - not sure I'll succeed with that but I'll have a damn good go!!
DS1 can already get his own laundry into the basket, knows how to empty the dishwasher, can put his own dirty crocks etc. into the wash, even knows which ones don't go in the dishwasher. He helps hang out the washing, so knows how to hang it on the airer (can't reach the line). He's 6.
DH can, and does, cook. He can, and does, wash up. He can just about get things back in the cupboards when forced to, and he does his own ironing. That's kind of it, in the house. We share DIY, he does the mowing, I make him do the ceiling light bulbs because we have 10' high ceilings and I'm not happy up ladders.
