jjkm, am I right in understanding you haven't had children yet?
Cos some of your posts sound wonderfully naive. I am not saying people shouldn't have an opinion on parenting matters if they don't have children, only that your view of the world will inevitably change based on your own personal experience of being a mother. Of which you know nothing about right now.
Still- I wish you luck. I should only offer a word of warning so you go into it with your eyes open: for a few months/years you will "do nothing but change diapers, mop, scrub, etc", AND you will occasionally be " miserable, stressed, or otherwise depressed". This is the reality of mothering small children, regardless of your socioeconomic or employment status, and the reason, I think, why websites like MN are so successful.
Personally, if I have to direct my energies and times towards something, I'd rather it be a job with money attached, as well as benefits and pension contributions, not to mention some degree of professional validation if I am lucky, rather than a "hobby". That, to me, sounds really very reactionary and diminishing of your abilities as a woman, but then I concede I have zero talent or inclination for anything artistic or athletic or crafty or housewifey.
