How and why is esperanza changing events in chapter potatoes?

Esperanza’s emotional maturity becomes increasingly evident after Mama gets sick. Without any prompting, Esperanza takes on the responsibility of being Mama’s primary caregiver. She understands what needs to be done instead of having to follow someone else's instructions. She asks Miguel about getting a job. Although Mama's illness is a setback for the family, it forces Esperanza to mature much more quickly than if Mama had remained healthy.

Meanwhile, Esperanza displays an rigorous work ethic while removing the potato eyes. She does not complain about the harsh conditions - she does what she needs to do to take care of her family. If she is overwhelmed by the foreign task, she does not show it. Instead, she looks to her elders for guidance, respecting the importance of the hard work.
