SAHM here too. Tried working part time from home, didn't work out with my line of work (legal research & drafting for law firm, clients expected availability whether I had a sitter or not... decided to take a break while everyone was still happy). For me, staying at home is more exhausting than office work, but more rewarding, and *usually* less stressful (not today, not this week, but usually...). The biggest drawback for us/me has been the effect on gender roles in parenting & housework (definitions of "helping" and "Work" with a capital "W"). It's a work in progress. I hope I'll be able to continue.
