Blood means nothing... Mother is a person who cares for you since your times when you can be hurt easily, not the person who delivered you :) I am glad you put her in front of yourself and take care for her. The real "mother" is very bad for that reason to abandon her. She doesn't have the strength to care for the young one because of her selfishness. It's a shame, really :( I believe with your help she will grow up to an amazing lady. :)
