My daughter ask me why her birth mom gave her up for adoption?

Because they realize they are not capable of caring for an infant at that particular time of their life. Perhaps they are not financially able, or not in good health, or any number of legitimate reasons. A mother who allows her child to be adopted gives the child the opportunity to grow up in a secure and loving family environment. She is not doing it to make her life easier but to make the child's life better, it is an unselfish, courageous and loving act.
