I realize it's been awhile since you posted this, but here's some more food for thought:
The JOYS of pediatric nursing
If you stay in a long term position, seeing how kids grow and change (yes, this has its drawbacks as well).
The coworkers--these are people who aren't just in it for the buck, they're in nursing because they care.
Every once in a great while, you get parents who appreciate what you do and actually respect your professional opinion.
Smiles when the pain gets better (okay, so it's when they're going out the door and going home, but it's better than nothing
--or when they've successfully given their own insulin injection for the first time, learned to walk with crutches after surgery...you get the picture.
The beautiful smiles when their hair grows back after chemo, or their scans/tests come back clear.
All in all, it's the toughest job you'll ever love. Sometimes you have to change and do something else, but that's the plus of nursing. When I first left Peds, it was because of management and other issues; I missed working with kids. I love babies, too, so I get a nice age mix in the position I'm currently in. Peds will always be my first love, no matter where I wind up.
