DD's took about 5mins to stop pulsing, it was in my birthplan but the MW supported it anyways. DD had a pretty short cord so she was laying a bit lower on my chest, and once it stopped pulsing and the MW was going to clamp it, the ends of the clamp looked like scissor handles, and I kept saying 'no no DH is going to cut the cord' and she kept looking at me then going to clamp it, where I thought she was going to cut it! DH finally goes 'chill out it's just the clamp' ha ha I couldn't see what was going on - felt like a doofus! Placenta took about another 40 mins to come out (naturally).
