I began nursing school this fall after being a teacher for almost 10 years, so I guess I have experience on the other side of the coin. While I liked being a teacher for a while, it was a lot of work. Sure, the hours are good and you get time off, but you spend a lot of time outside of work doing lesson plans, grading papers, etc. I am so glad that I made a change and should have done it long ago. Nursing school is tough and time consuming and you get a lot of experience in different areas, so you may find you will be interested in other areas. Unfortunately, most nursing programs give you general clinical experiences, so you probably won't get much experience with pediatric oncology. Like SCRN1 said, there are so many avenues to go in nursing. Go with your instincts and you will make the right choice. Just don't go into a profession because of the hours or the time off because you may find that you are not happy.
