People lean differently, but I believe that any nurse can transition to any specialty with good mentorship, guided hands on practices and in a conducive learning environment. Not in a rushed teaching environment that exists these days.
Transfer to labor and delivery first. Then you could transfer to NICU after 1 year or so.
check and see if your hospital or another have an internship program. L&D teaches you about labor and delivery, not about caring for a baby in the NICU. Newborn nursery will teach you about healthy, normal babies. Become an expert in NORMAL and ABNORMAL will jump out at you...most teaching hospitals do a great job with NICU transitions, as they are used to teaching and explaining why and what
Most hospitals offer an internship for specialty areas.
They'll probably want you to have experience with babies. I would recommend going to Labor and Delivery or Mom and Baby first and then transitioning to NICU when a position becomes available
