We are going to go with http://www.cordblood.com/ Here's some info I stole from their website:
Cord blood is the blood that remains in your baby's umbilical cord after the cord has been cut. Doctors have discovered that cord blood can be used in medical treatments. It can be used to regenerate healthy blood and immune cells in cancer patients and cure the following diseases: Leukemias, Lymphomas, other Blood Cancers, tumors, Inherited Immune System Disorders, Inherited Metabolic Disorders, Myelodysplastic/Myeloproliferative Disorders, and Histiocytic Disorders.What's really cool is that if we are able to afford to bank our first babies cord blood, the cells in that one baby's blood can be used on all of her siblings!
Cord blood banking is an once-in-a-lifetime opportunity for parents to collect and preserve the stem cells from their baby's umbilical cord blood for potential medical uses. By saving your baby's stem cells with CBR, your child and family can have access to better medical treatment options or cures for cancers, as well as potential treatments for conditions such as brain injury and juvenile diabetes.
If you decide to donate, I want to thank you right now. Having cute clothes and a nice high-chair for the baby is cool, but being able to save a life someday is really awesome! Thank you.
