no idea what happened with DS (DH can't remember either) but he was born on an MLU and I had a physio 3rd stage - does that mean his cord would have been left pulsating?
He was lightly jaundiced but I'd already read up on it so wasn't worried. We were told to leave him by the (closed) window as much as possible (so as to "sunbathe" him but not in direct sunlight) and that sorted things pretty quickly.
Probably having a homebirth this time round and will ask for delayed clamping.
As far as I'm aware, it's quite common for newborns to be lightly jaundiced, and if properly managed that's not a problem at all, and not a good enough reason to clamp the cord immediately.
A friend's first-born was a bit jaundiced, and some idiot of a midwife told her not to breastfeed! As a first time mum, she went along with that and was sorry later.
