Hey There! Congratulations on your new bundle of joy!
I'm sorry, I don't know much about cord blood banking, I was diagnosed with ITP at the age of 16, and just wanted to throw out some advice for your mother-in-law. it's the platelet disorder support association, a page for people with ITP and their families and friends.
Another word of advice: I had taken Prednisone, done different blood fusion treatments, and was even at the risk of having my spleen removed until I found Transfer Factor. I currently take Transfer Factor and have been in remission since I started taking it. I'm not guaranteeing that it works for everyone, cause I have found that with ITP, different treatments work best for different people; however, it did work great for me. If you or your mother-in-law would like some more information, feel free to write me.
