That is amazing! And really a miracle for that family!
I can’t recall where, but late in my pregnancy last time I read somewhere that the chance of needing the blood that you banked is very, very small. Like to the point of you needing a different babies cord blood is actually higher. So I would suggest possibly donating your cord blood. Whether it be for research or another child in need, consider it banking karma if you can’t afford to bank the real thing.
