To be or Not to be a Work at Home Mom

Not everyone can afford (due to fianancial, social or mental reasons) to stay at home with the kids. I, for one, am one of those. And as much as I actually enjoy working, I still cannot completely shake off the feeling that I need to have more time with my son. I am still looking for that work-life balance that I have been seeking for 3 years now.
An option, for someone like me, is to become a Work-at-home mom. But, am I really ready to quit my job and become a freelancer? Am I suited for this? Do I have what it takes?
Sitepoint's Fire your Boss! The Successful Home Freelancer's Guide is a great start to assess one's self (if you are in a crossroads like me). It asks the right questions (which we should be asking ourselves) and outlines what should be considered before taking that big step.
I should have my answer within this year. What about YOU? Would you consider firing your boss?
