Sometimes being a parent isn't all about you.
Actually, most of the time it isn't about you
In my opinion, you've gotten your "chance" to pursue your dreams, evidenced by the fact that you have previous degrees. While it's sad that maybe it wasn't your super super ultimate dream, it's not really a sad tale of whoa of an uneducated woman who just wants to educated herself. It's a tale of someone who wants to be a nurse.
Which is cool. That's why we're all here. But you have a FOUR MONTH OLD. Be a patent and a wife. It's what you signed up to do. Work on getting into programs closer to you. I know you have been, but nursing school hasn't disappeared and it'll probably still be here even if it takes you another 3 years.
And really, I don't know why anyone would be "in it for the money." There isn't much money there, compared to other things you could do with degrees.
