Who is the protagonist in "Lullaby"?

The central character in the story is Ayah, and she is
obviously more sympathetic than her husband, Chato. Ayah is strong, and she endures
despite all the adversities she has experienced. Somehow she lives through her many
childbirths, and in order to keep Ella and Danny with her she takes them up into a
mountain, where she tries to shelter them until the doctors and police take them from
her. She somehow blames Chato for this, and has nothing to do with him for years until
he is infirm and needs her to sleep next to him to keep him warm. Chato has not been as
much of a rock as Ayah, but for many years he had worked seriously to keep his family
housed and fed. Regrettably, when his work collapses, he gives in. He squanders his
monthly check to get himself drunk, and at the story’s end it is clear that his life is
over.
