Banking Cord Blood

This is something I've thought about before and then today I saw a phamphlet in a doc's office. Has anyone here had experience with adoption and banking cord blood? At first I thought this was over the top. Now I'm thinking if you don't have a "full" medical history for one or both bparents that this could be a literal lifesaver if an illness ever God forbid presented itself. If you do have exp. with (or even if you don't and you think you could lend some advice) how did you first approach this topic? I'm fully aware that every eparent has the right to choose parenting before TPR, so it might be a small financial loss on our part if that would happen. I'm also thinking this probably wouldn't work with last minute matches with little time for discussion or preparation. (Maybe not, I'd have to research specific companies more.) Birthmoms, would you be completely put off with this thought or look at it as a positive medical step for a child's future?? Any thoughts would be appreciated :)
