Aysel - the dream to be healthy .

Hello friends .
I write to You , because a lot of questions and scared because I do not know how to be , because you do not know .
In 2012, the doctors said we needed a second child ,a healthy to cure Aysel ( my oldest daughter is patient of thalassemia ), we tried ,did everything, and a miracle happened,was born at Aysel's sister Leila in 2014 , we were happy. doctors advised to preserve the umbilical cord blood at birth, Layla's ,and then advised such transplant using cord not to do ! it was hard for us to understand why we still a child ,when Aysel need to help with treatment .
Soon we will go to Moscow for examination, Aysel , and check out Leila as a bone marrow donor. I'm really scared , do I need to do a bone marrow transplant??? very afraid of losing her, Aysel , after all, the goal in my life to help my daughter to recover .
Friends advise how to be ? how did You have?
read Your posts on the forum there are parents who have already done a bone marrow transplant ! please advice 

djema,

my daughter just had bmt last year. BMT if not scary as you read from internet. BMT is not surgery, only like blood transfution. more younger patient, better for bmt candidate. I encourage you to do as soon as posible, if financial and every thing is ready.

thank you , You rock!!! Health To You !
