It was not hard to start in L&D, it was what I wanted from the moment I started nursing school.
I had 12 weeks of orientation on a very busy unit, it was more than enough orientation, but if you get hired on a smaller unit you may need more time on orientation, the unit I work on now the new grads get 16 weeks.
I care for 1-2 labor patients at a time, depends on where they are in labor.
There is no such thing as "typical" in L&D. Our nights vary from no patients at all, to all 13 rooms full, and someone delivering in triage. This has all happend in the last 3 weeks! Each unit is unique, the last hospital I work did 6000+ deliveries a year, the one I work now does about 1200+ a year, a big diffenrence in staffing and pt flow.
If L&D is what you want then go for it!
