Neonatal Nursing or Nursing Informatics

I am an Associates Degree prepared RN (May 2008), expecting to graduate with a Bachelors Degree in Nursing in May 2010, with clinical experience on a Med-Surg + Geriatric floor at a local community hospital since June 2008

I love working with computers, and I am considering further studies in Nursing Informatics or Neonatal Nursing.
The nursery was the best part of my rotation. I LOVE babies!

I need to switch jobs soon! I am suffocating at my current job.

Is there anything neonatal nurses or informatics nurses may see fit to share with me, and others like me?

Thank you in advance for your time and effort in replying to this post.
Recruiters want you for the area you're already working in - in my case med-surg. So, what if I want to switch to neonatology or informatics? Is it really that tough to train a med-surg nurse in another area?
