I really think a lot depends on how demanding your baby is and whether or not you have a natural inclination towards housework/cooking.
I used to think I had a demanding high-flying job until I had a demanding baby. I took a year off and it was utterly exhausting. I also have a very demanding, high-maintenance husband who expected a perfect home, gourmet dinner and knock-out glamorous wife with a cute fast-asleep baby when he got home.
I think men who have no experience of babies can be very unrealistic.
When I went back to work it was like being on holiday after looking after my baby. My "stressful" job with "long hours" seemed like a joke compared to what I'd been through ( my husband never, ever got up in the night for feeds).
To avoid arguments, I would definitely recommend the suggestions for careful tumble drying and non-iron shirts. Also, if you have a rather anal husband like mine, I find it useful to plan the weeks meals in advance so that a. you can sort out the shopping in one go so it doesn't eat into your time too much and b. your dh knows what to expect.
I was lucky enough to have a brilliant nanny for a while who gave me a really useful tip for tidying, she said when she was moving from room-to-room with baby, she'd always do a 60 second tidy of the room she was leaving (if it had got into a bit of a state). Once you're in the habit of it, you don't even notice you're doing it and it really helps you keep everything organised and hold back the chaos!
I found that both me and dh had to do a lot of adjusting within our marriage after my ds arrived. We both had to give in a bit to make it work.
I have to say I think it's pretty mean for your dh to go out all day on saturday and leave you home with the baby again. Mine did that too, but if it's any consolation, he most sincerely regrets it now and feels that he wasted a lot of golden opportunities to enjoy time with our ds while he was a baby.
Good luck xx
