FNP School

Hello,
I am considering going back to school to become a FNP. However, I have a 2 month old at home and I work part time as an ER nurse right now. I am considering the spring 2015 program which is about 2 years or so doing part time studies. Just wondering what everybody's opinions are on this... Not sure if I should wait or just do it. Also, if I do complete the program, I'm not sure I would want to work full time. Are part time FNP positions hard to find and would it even be worth it? Thanks in advance.
