Thanks so much for your replies, and thanks Kelly for posting Sarah's message.

Unfortunately we are still undecided on what to do. DH is one that likes scientific proof and details on both options. A few years ago I donated bone marrow to a baby with leukemia but unfortunately she died. This is what got me thinking to donate the cord - the chance to save another life. But I don't want my baby missing out on the blood if she needs it.

Will do some more research and thinking on this....
