Hi mummies, is cord stem cells necessary? Or just cord blood will be good enough? If I would to buy both, the cost is quite substantial.

I think necessary is an over-statement. Depends if u really believe in this whole cord banking thing - it does work but chances are slim. It's a luxury to have I feel. So if it's cost is too much for u to agree on then I say just don't need? By the way, in the future if u regret, stem cells can be harvested from baby tooth too
