Congratulations to you!!
My first nursing job after nursing school in 1991 was in a Well Baby Nursery too. About 6 months later our Well Baby Nursery combined with the Postpartum Unit to become a Mother-Baby Unit with couplet care and I loved all of it. I suspect you will too! I loved the teaching part helping parents learn baby care and things like that. After about 7 years I transferred to the NICU where I continue to be very happy and know that without a doubt my previous experience has helped me be a much better NICU nurse as I understand more about what the mother's are going through. Many of my postpartum patients were mom's who had babies in the NICU.
There are some absolutely wonderful suggestions here for you and I agree with them all. I will suggest a book for you though which I absolutely adore and think you will find very helpful in assessing newborns. You can get it on Amazon.com:
Physical Assessment of the Newborn: A Comprehensive Approach to the Art of Physical Exam, by Ellen P. Tappero & Mary Ellen Honeyfield, 4th Edition.
This is a excellent book in more ways than one. Great photos. Detailed explanations. Rationales and reasons why certain things are as they are. All kinds of great stuff! Very much worth the $54.00 price. Please check it out and consider using a bit of one of your first few paychecks to buy it. I feel sure you won't ever regret it.
Wishing you all the best and a career as rewarding as I have had so far! There are many supportive nurses here who are always able to help you as best we can if you ever have questions about anything.
