I feel its more about how an individual has been brought up and what he wants to deliver to his or her kid. To me, it really doesn't matter that the child is biological one or not after all that small one is a human being. In fact, adopting child gives the reason for parents to feel parenthood and blessed life to small ones. Isn't this is an amazing feeling? There is nothing to hide about adoption. If you are adopting a child be proud of it. After all, you are giving meaning to someone else life. Take Care....
