Cord Blood Banking for a Second or Third Baby: Worth It Again?

Once you've banked for one child, the decision for the next isn't automatic. The math changes a bit when you already have a sample on hand.

More samples = more match options

Siblings have a roughly 25% chance of being a full HLA match and a 50% chance of being a partial match. Banking each child's cord blood multiplies the chances that any family member who needs a transplant will have an in-family match.

When parents skip banking the second time

  • There's no relevant family history of treatable conditions.
  • The first sample is already large and high-quality.
  • The cost of multiple ongoing storage fees becomes meaningful.
  • Public donation is available locally as a free alternative.
