I think people do not realize that blood is the lifeline of human being. Cord blood banking has the cells frozen at the youngest age possible. Cord blood rich with stem cells and immune cells and exosomes can be infused back to the baby herself or himself for the rest of her or his life. Because it is his own blood, just rich with the youngest and healthiest cells of every type. So theoretically, the cord blood should never be wasted. Ten years ago, there was no cord blood treatment for cerebral palsy. Now they do. Just ask thousands of families around the world. Science develops, but for the children, they only have one chance to bank and they cannot even make this decision without being represented by the parents.
