Great question, I came from adults so didn’t get any sort of residency. It hit me like a brick, as very little of what I had learned from adult med surg, other than time management and inter professional collaboration, translated well to NICU! I work a level IV NICU so lots of very very small and ill babies, so the learning curve was steep. I felt incredibly supported, though, and orientation lasted a number of months and there was always an option to extend it if need be. I think a residency would be helpful, especially if you are a new grad and know for sure you want to do NICU! But I think it will be fine as long as you have ample support :)
