Yes, because each baby's cord blood is an exact genetic match for that child and offers the very best chance of survival, with no risk of GVHD, should they need a stem cell transplant in the future. Also, in the event that a doctor recommends a donor cord blood transplant, siblings are the preferred source. Lastly, there is approximately a 1-in-4 chance of parents being a match to each child's cord blood. Storing for multiple children increases the chance of a match being available for parents. Separate storage is also recommended for multiple births (e.g., twins, triplets), as it maximizes the volume of cord blood collected.
