There is the argument that delayed cord clamping increases red blood cell load and so increaqses the risk of jaundice that will need treatment. One question I have is with the argument about increasing the amount of stem cells the baby gets, is that blood pumps out into the cord as well as into the baby, so I don't see how it would increase the levels of anything really. Also if baby comes out in obvious distress, like meconium being present, no respiratory effort etc, they will clamp straight away so they can help bub.
