Peoniesarepretty. Delayed cord clamping is leaving the placenta attached to baby for up to a couple of hrs or until cord stops pulsating. If left attached the contents of the cord are absorbed into the baby body. I don't know scientific research/benefits but if have a look you should find them, I do believe they have done some documented studies.The belief is though that the cord is full of amazing cells, nutritions , blood and other goodness that benefits bubs. It's like a natural vitality boost and some belief it enhances immunity and reduces likelyhood of future allergies and alike.Unfortunately its not std practice in most hospy so you need to make ur intentions clear early on.
