ER to NICU

I have been an ER nurse for over 6 years, med/surg 2. I have recently accepted a position in the NICU. Terrified and excited at the same time. These babies can be very sick. I have no presumption that it is all roses and rainbows. Excited because I have wanted to be part of the NICU team since I became a nurse. Terrified because there is so much to learn. Maybe terrified is to strong a word. I don't think this is a bad thing to be terrified/nervous about it. It just means to me that I am going in with the right attitude of I have a lot to learn. I went to the hospital library and got a few books to study up on. Thank goodness they have them cause they are expensive, and its hard to choose which one is best. I got a book on Neonatology - management, procedures, diseases and drugs, the on from AWHONN - Core curriculum for Neonatal Intensive Care Nursing, and I believe the Merenstein & Gardner's Handbook of Neonatal Intensive Care. Any other suggestions to familiarize myself with this area of nursing? Thanks for the help.
