We are going to bank our baby's cord blood.
Private cord blood banking is a form of health insurance and security for both our baby and our family, so it's money well spent. It is expensive, but we made it affordable by setting up a gift registry at CBR to let our family and friends help defray the expense by contributing. And we saved another $250 with the gift code at

If you think about the money you may be spending on your baby, for example for childcare which could be $500-$1000 per month, an investment like this, for something that could save a life, falls into perspective.
Donation is a great alternative, but the odds of finding a good match from a public bank should you want it aren't great. The stem cells from your own child are the best match.
