I am someone who has been on both sides of the fence. I've had that wonderful corporate job that took a lot of time away from my family. Believe me, in the corporate world I worked in if you say "no" one too many times, you will be left behind and you will feel it. So I don't know how that could possibly be fullfilling. I juggled this for 14 years.
I've been a SAHM for the last 2 years. I have a 16 yo, a 7 yo, and a 2 yo. There is no way I could work full-time, and be here for them like I need to be. I understand the "need" for 2-incomes, but honestly we are not that much worse off financially than when I worked full-time. You save quite a lot by being a SAHM - no daycare, no commuting, no dress wardrobe, no lunches, no office contributions.
And how could I possibly feel more fulfilled than when my 2 yo says, "I love you, Momma," at 9, 9:05, 9:15, 9:30, 9:35, 9:40, 9:50, 9:55 ...... " and this is just the first hour of our day.
And when my 16 yo dd wants me to take her and her friend to a Good Charlotte concert and it's okay to bring her 7 yo brother? And her best friend thinks I am the most wonderful mom in the world? And they have no problem going to mall, the grocery store, and the library with me and her siblings?
Yes, my job is much harder now. Believe me, you get no coffee breaks or long lunches. But to me, this one is so much more fulfilling - I am truly shaping the future.
