I am not a SAHM, mostly because I'm not a Mom yet. I hope to be a Mom this year, can't see me being a SAHM unless we hit the lottery. I do project work and most of the time have some flexibility to work from home occasionally. My firm does have 100% home based positions, but I'd probably have to take a pay cut. I don't think I would want to be 100% SAHM, I would probably go a little batty
But, I hear that your whole world changes once you get that bundle of joy in your arms.
