What are three examples of how Juana is in control of her family

Juana is in control in the sense that she protects her family, such as in the way she protects the baby and tries to suck the poison out of his wound.

Juana is in control in the sense that she expresses her feelings about the pearl and the danger she believes the pearl represents; she tells Kino she wants the pearl thrown back into the sea.

She is in control in the sense that she supports her husband and what he wants to keep the family together and safe. She is the foundation for "The Song of the Family" and that is a significant role in the story as the family goes through its trials.
