To be honest...before having a child yes I did. I didn't understand it by any means, but then again, the examples of working moms I had around me I think just were't meant to be moms in general. They say that themselves and their kids don't like them (my cousins don't talk to their mom). So in a way I think I was sheltered growing up in a home w/a SAHM, I couldn't imagine it any other way, blah blah blah. That's how all my friends were too.
NOW, w/a child, and having done school fulltime for his entire life, I needed that break to be "me." I adore being a mother, I really do, but I now understand working moms. Some moms are great at being home, and some moms are great at working and being a mom. For me it's about finding out which I am better at. I truly admire working moms now and kick myself for ever viewing it otherwise.
