I have to admit that I'm struggling with the idea that as a SAHM you can't get all the household chores done in an 8-hour day and still have time to get dinner on the table.
When I was on ML, it only took 4 hours pw cleaning the house, once a week only. And then another 3 hours pw to do laundry, ironing etc. I would then have all my HH chores/tidying up done by 10am, leaving me all day to meet friends, shop, take DD to groups etc, before heading back home at about 4pm to start dinner. And that was with a very small baby to juggle - all the feeding, lack of sleep etc. I was up at 6am every day to manage it though - but that was my choice to get up earlier so I could have as much free time as possible.
Its harder now that DD is a bit older, but we role-swapped for a year until she was just gone 2, and my DH found roughly the same was true. As soon as DD was old to crawl, she had to help clear up after she finished playing, clear the table etc.
We are both anal types though so like to run things a bit like a nice bootcamp
The big thing that did make this manageable though was an unwritten and unspoken agreement about what was within the SAHP job description. Things like sorting the gardening, DIY, buying things like clothes for DD and stuff for the home were absolutely out, and were shared equally between us in our free time.
Cooking is a pleasure for both of us, so we also had a cooking rota - which included one night a week of "easy" slam in the oven night, and one takeaway or eating out night.
Lots of stuff done online as well - banking, bills, research into things, food shopping - all makes life much easier. And these jobs were (and still are) shared between us so that I now do half of them whilst at work (they take 5-10 mins each and everyone deserves a bit of downtime even at work)
Having said all of that, Hai, your husband sounds like he needs a good kick up the jacksie. What was his home arrangement before you met like? Did his Mum do everything?
