I would take the full-time L and D. You are clearly passionate about perinatal nursing and it will definitely give you good experience for family health, though not so broad. I would advise against doing both PRN or Float Pool nursing right out of school. You want to spend 36 hours a week immersed in patient care right away so you can retain everything you learn. Float Pool nursing is for experienced nurses who have a broad range of skills and are ready to adapt to a different environment every day. For new nurses, routine and repetition is everything! Good luck with the decision!
