Should DH and I use a cord blood bank and save LO's cord blood in case he ever needs it? It's pricey. We can afford it though, without sacrificing anything. Is this really legit? Do they REALLY save it in case you need it? Could it be a scam? Should we do it? My instincts say yes, but would love opinions, as I'm not totally sure. Thank you. This place has been a life saver for me.
