I have been working NICU for only 3 months, but the first couple of things I had to do was attend a S.T.A.B.L.E class and become NRP certified. The textbooks for those two courses have a plethora of information in them that you could begin reading up on if you wanted to make the investment up front. I was provided the textbooks by my employer for a temporary use, but I think they would be great resources to have in my personal library as well. Here are a couple of links to these books on Amazon.
