When you are a nurse, you know better than most anyone else that life goes on. There are good days and there are bad days. There are patients who stay with you, and those you can't wait to forget. But there is always another mother in labor, or delivering, who drives you forward. There is always a new crop of tiny humans who haven't even written the first sentence in the story of their lives. The process of birth is such an assembly line, in fact, that it always surprises me when I am forced to stop and look twice - like when a baby I helped deliver seemingly yesterday is suddenly my patient, about to have her own child.
