S.K.
I have not privately stored any of my childrens' cord blood, but I just received my kit for donating the cord blood of my 4th baby (due in 4 weeks). Public donation of cord blood is like regular blood donation. If you need cord blood in the future you don't have access to your own, but you have access to many, many units of cord blood that can all be tested to match your child. Even your privately stored cord blood is not necessarily going to be a match for your other kids in the event that you need it in the future. And, of course, public donation is free. It is so much better than wasting the cord blood and is an immeasurable public service.
With your due date fast approaching you would need to call and see about getting a kit ASAP, if you are interested.

Congrats on the upcoming birth.
