We did not donate because of the extra cost. I heard about a bank that would accept the donation and if your family ever needed some that you would be able to get some but it wouldn't be the cord blood you donated. I know there are a lot of great programs out there. Ask Jeeves...he normally come up with great info!
I personally felt that my baby was the rightful owner of that blood and it would benefit her to have it all, so we didn't cut the cord until about an hour after birth.
