Advice for a future Peds nurse

[CamMc]

Hello, I am working on returning to nursing school. The school I am more than likely going to end up with (an ADN program at my local community college) has a two year wait-list so I definitely have some time, but I am almost 100% certain that wherever I end up in nursing, I want it to involve peds. When I was in nursing school before, a little over 10 years ago, I had gone in knowing then that I wanted to work in peds and I feel like my determination to just be in peds made it harder for me to focus and learn in other subjects. There was a lot of other things going on at the time in my personal life, so I feel I have matured and am fully prepared to put my full heart and soul into learning about all aspects of nursing, but am looking for any advice on either certain areas of nursing that it may be more important to really learn (skills, body systems, etc) or anything that might help me be better able to get a job in a peds unit when I'm done with school? I am already thinking that when I get closer to nursing school I will get my CNA and hopefully get a job at the local Children's Hospital (I'd do this now, but need to keep working at my current job for at least another year because of the pay.) I have several years experience working with children with autism and other intellectual disabilities, including having my master's in applied behavior analysis. I'm definitely open to working in a behavioral unit, but I worry that starting in a behavioral unit would limit me to staying in behavioral. Would love any advice that could be helpful at this point in my journey.
