I've been off orientation for 6 months now, and I felt just like you when I became "full staff". WeeBabyRN is right. You're never alone in the NICU. No matter what has come up for me in these 6 months, my charge and fellow nurses have been there to support me when I needed it. Looking back at the last year, I am amazed at how far I've come and still awed by how much more I have to learn. You'll be fine... just never be afraid to ask questions and get help when you need it. Best of luck to you!
