In the traditional family dynamic, parents often make decisions for their children with the belief that they are acting in their best interests. This approach is based on the assumption that parents are in the best position to understand and prioritize the needs of their children. However, this mentality can lead to complications, particularly when parental decisions favor one child over another, causing an imbalance in the family system.

Jodi Picoult's book "My Sister's Keeper" explores the ethical dilemmas that arise when parents prioritize the needs of one child at the expense of another. Such favoritism can blind parents to the unique needs and rights of each child, leading to a breakdown in family relationships. The story illustrates the complexities of parental decision-making and the emotional fallout that can occur when a child's well-being is overshadowed by another's interests.
