Second degree student with a baby

Hi! I have been taking prerequisites to attend nursing school for nearly 4 years now. I already have a bachelors in healthcare administration and I work as a patient experience manager. In my work with nurses, I have been really drawn to the field. I finally got accepted to start the program this fall. I also have a one year old and I am currently the breadwinner/benefits provider for my family. I have a few questions for those of you who have been through this because I am wondering if I should put this dream on hold for a few years. Is it reasonable to think I can do school, work part time, and be a mom? We want to have more babies- how long after starting a career as a nurse would it be reasonable to take maternity leave? Is it harder to go back once kids are in school?
