… from either delayed or immediate cord clamping?

Either is fine, although I highly recommended delayed cord clamping/cutting because of the benefits to your baby. Waiting at least 2 minutes or until the cord has stopped pulsing can ensure baby receives the 30% of its blood that is still circulating through the placenta and cord (outside of its body). This volume of blood belongs to the baby and is rich with all the oxygen, iron, red and white blood cells and stem cells your baby needs for the very best transition from the womb, and an optimal start to life.
