That's a great question....Working full-time and being a wife and mom definitely makes it hard to find balance in life....it was much easier when we lived in an apartment too, b/c now we have to juggle house things as well...
DH and I definitely have some "defined" roles---he does most of the "outdoor" work and I do more of the "indoor" work so to speak. It's just what works for us. Neither of us really complains about, it's just what we do. I definitely think that if I was a SAHM, I would do a lot more of the outdoor stuff at home as well, but I guess I can't do everything (right?)
I do feel that the one thing in my life that suffers is IRL friendships which is why iVillage has become very important to me. It's hard to want to go out with friends at nite when I'm dead tired by the time I put my 3yo to bed!
