what is the author most likely purpose for introducing the story through madame valmondes Point of view

Desiree's Baby is written in the third-person (omniscient) point of view. This point of view allows Chopin's readers an intimate look and the thought and actions of each character. Madame Valmonde is Desiree's mother. Desiree, as an abandoned infant, was a gift to madame and her husband. She loved her unconditionally..... she was colorblind and without bias or prejudice. Thus, the ability to see the story through her eyes provides an intimacy we would not have if someone else were narrating. Considering the other characters, Madame Valmonde seems the most reliable.
