Signing in Iota!
I also did the 2 parents working all the hours god sends when we had one child, and gave it all up when No2 arrived as it just wasn't worth the stress. Financially it means dh can concentrate on his career, which means he's right at the top of it and can earn more on his own that we could if we were both working but having to concentrate on home/kids as well. And hopefully he'll be retired in 10 years so he will be able to spend lots of time with the kids and me.
And I really don't see why I m setting a bad example to my dd or ds- I had a career, my hard work and qualifications earnt me a considerable amount of money and respect for 12 years, and then I made a choice to make a change. They now see me being a homemaker, a supportive partner, a voluntary contributor to the local community and an educator - none of which I am ashamed of. They also both know that I worked before having kids, and that it's possible to work as well as having kids.
