I've been wanting to be a nurse for 10 years now. I first decided when I had my first baby but had just graduated with a BS in education so I had to give that a try first. Did that for a few years then tried to take the prereq's but due to kids (three at the time) and working full time as a teacher, I couldn't do it. Finally, after having baby #4 two years ago, I was able to stop working and do the prereq's. Just the prereq's mind you, not nursing yet. THat was difficult in its self because of no child care. Now that my baby has just turned 2, he'll be going to daycare so that I can finally go to nursing school. My other boys are 7, 12, and 14. Thinking back, I should have done this so much sooner but I couldn't or didn't because I didn't want to cause friction, if you know what I mean. I know that it'll be hard with 4 kids but I have to make it work. So I suggest that if you don't have to work, do it now while the kids are small. My older boys are so busy and I'm constantly running up and down. And if you already did 4 semesters, you know what the work load would be and if you think you could handle it, go for it. Good luck!
