My sister-in-law used to work for Cordlife and she has advised me to go public for cordblood banking for the 1st child. As usually, the 1st child will not be able to use back his own blood cells for treatment. Unless you have other children, would be advisable to invest & may come in use should any emergency arise. Like mentioned, if donate to public cordblood bank, can tap onto the pool to find a match.
