After talking to multiple professors, they explained how it is very hard to have fieldwork in a NICU because of how sensitive the babies are and because of hospital restrictions. In addition, I was told it is very difficult to begin your career working in the NICU because of the experience necessary and because of the delicacy of the babies. Just as it is difficult starting out in EI because it is good to have experience before going into an in-home environment.
I am also interested in the NICU, but from what I have gathered from talking to schools, the NICU is not a place to start out in as an OT.
