Placenta

Some people do interesting things with their kids' placentas. In the end, we left ours at the hospital, partly because Sachie didn't know what to do with it, and Sachie's mom thought it would be too grotesque to stick in the freezer. (Plus, we don't yet have a deep freezer.) Maybe with the next one we'll have a plan.

There's a company called LifeBank that will store the cord blood and optionally the placenta for later use. The service is pretty spendy, though, so you have to be fairly loaded to even consider it.
