On average, 2nd babies come a little earlier than first babies. But my second was in no hurry at all. My son was born at 41.2 weeks, my daughter at 41.5 weeks. With my son, I had lots of cramping in the weeks before his birth, with my daughter, almost nothing I could feel until just a few days before her birth. Every pregnancy, every birth is different in some ways from previous ones. But until you're 42 weeks, you're still within the average, normal range and there's nothing to worry about.
