It's cord blood donation, and yes, I did it with my DD's cord blood and plan on doing so with this baby as well.
I am not sure where you live, but there are different cord blood donation programs out there. I donate to the Dan Berger Cord Blood Program through Magee Women's Hospital in Pittsburgh, PA (USA). It is a wonderful program and has helped so many children!!
I heard about the program through my obgyn and immediately signed up.
So if you are interested in programs in your area, I recommend asking your doctor or midwife or hospital where you plan on delivering if there is a program in your area, and start from there!
As a side, you can also bank your cord blood for your own child's use. You do have to pay a fee for storage, etc. with that option, but I wanted to make sure you were aware of that option as well!
