Honestly, it's not fully either-or, someone in my mum group mentioned that delayed clamping and cord blood collection can actually be done together if you wait just a couple of minutes first, so you don't have to sacrifice one for the other entirely. The trade-off is that delayed clamping does let more blood (and clotting factors) transfer back to baby, which some mums felt was worth prioritising over maximising the volume collected for banking. Private banking gives you that "insurance" feeling but it's expensive and the chances of actually needing it are quite low, whereas donation means someone else may benefit even if your own child never does, both are valid depending on how you weigh peace of mind against practical odds. My lean would be to discuss the timing window with your doctor first, since some hospitals here are more flexible about combining both, and then decide if private banking is worth the ongoing storage fees for your family's situation.
