I'm a guy nurse. Been school nursing for 19 years. Worked on peds floor for 8 years prior to schools. I would recommend working in the hospital for a few years first. You gain lots of good skills there: how to think on you feet, how to deal with difficult people and people who are stressed out. You learn how to teach, you get exposed to all sorts of diagnoses. I enjoy my job for lots of reasons: I get to work with well kids, it's a great schedule (I work 192 days), I am well respected and am an important member of the team, etc, etc. So, go for it. Get through nursing school (my experience reminded me of basic training!) and then learn a ton of stuff when you start working. When you get burned out get your school nurse credential.
