Life has gotten even more unsure for stay-at-home moms. Its a high-cost vocation. With economic times as they are, the choice is becoming even more complex.
According to a Salon article titled "Regrets of a stay at home mom," it is becoming increasingly difficult to make the choice to stay home:

"The economic crisis will erode women’s interest in “opting out” to care for children, heightening awareness that giving up financial independence — quitting work altogether or even, as I did, going part-time — leaves one frighteningly vulnerable. However emotionally rewarding it may be for all involved, staying home with children exacts a serious, enduring vocational toll that largely explains the lingering pay gap between men and women as well as women’s higher rate of poverty. With the recession having raised the stakes, fewer mothers may be willing to take the risk. If it’s not yet the twilight of the stay-at-home mother, it could be her late afternoon. Certainly it is long past nap time."

Is it the twilight of the stay-at-home mother? It certainly seems so.   Between 2008 and 2010, the number of stay-at-home mothers fell from 5.3 million to 5 million.
I'm starting to wonder if the fact that women have achieved more career mobility and greater access to the working world is a curse as much as it is a blessing. Maybe, by achieving greater potential in the working world, women have created  a situation where women are indispensable as workers and can no longer make the choice for full-time motherhood.
