sissyboo I have been a preceptor the last couple of years and it was a very rewarding experience. I didn't get the opportunity to shadow a nurse while in RN school, but during my summer break I shadowed a pediatrician who also does NICU and I totally loved it....I knew then that was what I wanted to do. I am sure you will learn a lot and never ever be hesitant to ask questions...that you probably already know but it's how we all learn
