Diversification of Skill set/Experience

Hello all,

Just wanted to get some advice. I am a relatively new nurse. I graduated a little over a year ago and have been working in a pediatric primary care clinic since. I am really enjoying pediatrics but worry about limiting myself to this specialty. We see healthy and sick children but really nothing too intense. My employer is the only pediatric hospital in my area and they also own most if not all of the primary care and specialty clinics. I am wondering if it would be a good idea to try to get a prn job in adult care to both maintain my skill set and diversify my experience just in case. I am a good employee and don't anticipate leaving my job or getting fired but it just makes me nervous because it seems I'd have nowhere else to go if something were to happen in my current position.

I'd like to know your thoughts.

Thanks!
