I'm confused -- your title says you have a passion for being an NICU nurse, but then the post itself says your passion is to become a neonatologist. From your estimate of 14 years of education, I'm guessing you've sorted out that a neonatologist is a physician (MD). If you really want to be a neonatologist, that's what it's going to take.
However, if you're open to other possibilities for working in NICU, there are plenty of RNs who work in NICU settings, and also neonatal nurse pracitioners (NNPs), who are advanced practice nurses (more like physicians than "regular" RNs, but still nurses
). You could be licensed as an RN with as little as two to three years of college, and be eligible to work in NICU as a staff nurse, and NNPs have a few additional years of education beyond that (but still a lot less than 14!
Welcome to allnurses, and good luck with your research and exploration!
