What is the best and worst aspect of being a labor and delivery nurse?

I am a nursing student, and I am most interested in working in labor and delivery. I was just wondering what what the best and worst part of that unit is and if the burnout rate is high. I imagine the hardest part would be letting a baby go home with obviously unfit parents, and stillbirths. How often does this happen? How are you typically treated by patients? Do you HAVE to ist in circisions? In general could you just tell me anything you think would be helpful
