NICU nursing in the UK

Hi there,

I'm marrying a UK citizen next year and while we plan to make our home in the U.S. for a few years, there's also the possibility of moving to the UK a few years from now. One of my co-workers is British and was telling me that in order for her to work in a NICU, she also had to be a midwife and do L&D and post-partum; that she would have to rotate every couple of months or so, and that the only exception was that if she had worked in a children's hospital.

Is this really true? Do you have to work antepartum, labor and delivery, postpartum, and be a midwife in order to do any work in a NICU?

I've done some basic searches but haven't gotten much info. Thanks for any insight
