This is an interestng thread! I'm currently reading the book "Perfect Madness: Motherhood in the Age of Anxiety" by Judith Warner. The author is critical of the AP lifestyle (she says that it sets up high ideals that demand too much of mothers), but she also raises some great points.
The basic idea of the book is that American mothers ARE stressed because we have high expectations, little or no support, conflicting desires, and an insane culture. We were raised to believe that we could be great moms and be fulfilled at work - but really we don't have enough support to feel good about either role. We work really hard, we are competitive (because of the American culture of individualism and competitiveness) and we are stressed.
We think that we have "choices", but often our choices are just crappy. Be at home full time with your kids with little support or take a job outside the house and struggle to find decent childcare. Hmmm - crappy choice A or crappy choice B - which do you prefer??
I think stress is a huge problem in our society. We expect everyone to be busy, hard-working, productive (and STRESSED) most of the time. It's just unhealthy.
All that said - yep, I feel stressed. My house needs attention, it's freezing cold outside, I have a rowdy 2 year old and a high energy 6 year old, I miss being with adults more, etc.
Okay, my two year old is running around naked. I guess I should go give her some attention!
