I have to agree. Going to nursing school
is something that will dominate your life. Although you could keep much of the work within the children's school day, if you are going to school full time, many nights and weekends you will be studying. When you get to the clinical portion of the program, you will be putting in one or two days per week on 6 - 8 hour shifts in the hospital, plus all the studying.
I agree also that you should not drop this goal - you have been thinking of it for a long time, but to make it happen, you are going to need more drive and motivation than you have right now. Do make the visits to the local educational programs - both community college and BSN. And then just plain get started! Find out about some of the prerequisites - and just start taking them slowly, one at a time, just 3 hours a week (that is not much time away from your kids) as soon as this summer. You might find you enjoy school more as an adult and as the children get older, your desire to finish may grow and then you will take 2 or 3 courses at a time. Think about what you would want to do 40 hours a week if your life changed suddenly. If something happened and you were faced with having to support yourself, your children, and perhaps your husband, what would you be able to do? What would you want to do? If you think you would be happy nursing and miserable (and poor) working at a minimum wage job, you should start working toward that goal now - your are still young. Plus being in school while your children are in school would be great role modeling for them. Would you like your daughters to attend college? The highest predictor of a child's success in school is the educational level of the MOTHER.
If you never start, you will never finish....
