Sml, I think we've hit on the same routine, it's rather uncanny! Although I'm pretty impressed by your cloth/basin/loo arrangement and intend to copy it.
Copper, I too would think about cutting down the PTA involvement, but if you like it, that may not be the answer. The trick is to eliminate the things that really make you stressed and nothing else.
Like you, I have a full-time job and in my case, just the two children to come home to. The toddler, when he's around, makes so many jobs cry-makingly stressful to do, like cleaning with bleach, hoovering, and sweeping the kitchen floor. And then when he's in bed, I don't hoover too near his room in case he wakes up. Consquently his patch of stairway and hall carpet has a grey layer of grit. It realy upsets me just to think about it.
As for ironing, only for weddings and funerals in our house. I don't even have an ironing board. All clothes bought on the asumption that they can just be washed folded and/or hung up.
Also hide everything you can away in drawers, boxes and cupboards. And fill shelves with boxes of things, too. Display as little as possible. It just gathers dust.
I've always been a very reluctant cook. Since the second son was born, very quick or ready-meals rule during the week. I'd rather have a less-hurried bedtime routine with my children and then catch up on some basic housework while something cooks in the oven. Anything that involves standing by the hob and stirring for long periods of time is avoided.
My husband says he helps 50/50...hmmmm. Sort of, something like that, possibly, I think. He does like cooking though. Unfortunately for me, both he and my older son love a clean tidy house. My son even checks that I will be tidying his room before his friends come round. This has got to stop! Lucky you for having a family with such a nice relaxed attitude to housework.
And then there's the cleaner conumdrum: getting the house clean enough to invite a cleaner round. Like you, I've never had one so perhaps I am worrying over nothing. I phoned up some agencies but they were so expensive. Silly question, but how can you get a trustworthy cleaner privately for the odd one-off? None of my local friends have them so they can't recomend anyone.
Copper I too will be catching up with everything at Easter.
