there isn't any evidence that delaying cord clamping for longer than 60 seconds gives the baby more benefits than delaying cord clamping for 30-60 seconds
I feel like someone whose business is freezing cord blood should probably cite some sources when discussing guidelines for delayed cord clamping, which reduces the amount of blood left in the umbilical cord. Honestly, I don't know much about it and you could very well be right, but it seems like a conflict of interest.
