K.G.
We banked both children's blood with CBR. There is a history of cancer in my husband's family. His sister under went a bone marrow transplant in her 30s and had a very hard time finding a match; even as one of seven children there was not a match in the family. It is expensive, but compared to some of the alternatives we have had to witness it was something to which we are committed. I delegated the research and choice to my husband. He chose CBR because at the time our first was born, 3 1/2 years ago, they were the only ones who had made a profit yet. In his evaluation he felt most confident that they would still be in business in 10 or 15 years. While we hope we never need it we wanted to make sure that it is at a reliable storage company in case. I would advise you to take the same approach. Companies and management change over time so see if that information is still current.
And if you are not going to privately store it, I second the suggestion to donate it. We are incredibly grateful to the generous donor who kept my sister-in-law alive. (She is about to hit her six year anniversary of the donation.) There are many people who need it from the families that can share.
