I would not expect to come home and do 50% of the housework if I had a stay at home partner.
Actually I agree with this. And it was the case when I was a SAHM (and of course I expected the same treatment when DH was a SAHP for a year - helped him see what work was really involved and is something I'd recommend to any family, this swap in childcare duties, if it can be financially sustained).
I think women who stay at home either slow down and get used to doing less so find it harder, or the types who choose to stay at home could not cope with much anyway and that is why they are at home.
Be prepare to be flamed for that one.
But I think it all depends so much on someone's circumstances - it isn't as simple as "SAHMs are lazier/less stamina" which is what you're implying.
I will admit in a small that when I was a SAHM I found it immensely less stressful than going to work though
No deadlines, flexibility to have a break without being watched over, a lack of TOTAL regulation over timing e.g. if I decided I was too tired to take them to a playcentre that day,I could cancel and re-arrange - can't do that at work. I loved having no one to answer to every half hour, no regimented schedule - hell I didn't wear a watch most days! Can't get away with that at work.
I think that's something a lot of SAHMs don't admit to - yes it can be hard, and unrewarding, and other stuff - but it can also be fulfilling, easier than work, and better paid! (If you're making less money than you're bringing in due to wanting to keep your foot in the door.)
Whenever I have been on mat leave I also take care of whatever needs to be taken care of in the house (I have 4 children) and I have not found it a struggle.
Again this depends on your support network, how close in age the children are, and, dare I say it, your natural ability to cope? Not everyone is the same.
So - to summarise - I fear the truthful nuggets in your post will get lost in the MN chatter during your flaming for the other comments!
I thought I should post that I do agree you have some valid points though.
