Here is a video on cord blood collection
However, parent should get to hear from an expert too before making decisions
Some consideration thoughts before deciding on stem cells:
1) Cord blood have a possibility to treat leukemia or lymphoma, aplastic anemia, severe sickle cell anemia, and severe combined immunodeficiency. This is usually related to family medical history.
2) In most cases, stem cell transplants are performed only on children or young adults. The larger the size of the person, the more blood-forming stem cells are needed for a successful transplant. Umbilical cord blood stem cells aren't adequate in quantity to complete an adult's transplant.
3) Clamping the umbilical cord too soon after birth may increase the amount of collected blood, but it could cause the baby to have a lower blood volume and possible anemia soon after birth.
