maybd the evidence shows that yes it helps prem banies..if you leabe tje cord.to.stop pulsaring eventually he flow.equalises.amd the baby ends up with the blood it needd.
I have nevrr hesrd of too much bloof going back into the placenta and that is not what the studies say.
Maybe it wasnt explained very well to you or maybe your dd experienced an anomoly, i would ask for further explanation as it doesny make sense tbh!
Ultimately the health if mum amd baby are priority and delayed clamping isnt always posdible but for a long time the cord has been clamped immediately just because when actually the evidence is that it is better to have delayed clamping
as lonh as circumstances permit that.
And yed thr placenta not being attached to you may have made a difference, did the placenta abrupt?
