When my youngest was born, we kept the cord intact for longer than we have with our previous children. It was about half an hour, since the midwife didn't arrive until about 20 mins after his birth, and we didn't cut right away after she arrived. The placenta was the smallest of my kids' -- closer to a tennis ball than a dinner plate. I'm guessing it has to do with the blood getting to the baby instead of staying in the placenta, but I'm not sure. Anyone else know if this is the case?
