My Sister's Keeper
Blog 1
Parenting is different, physically and ideologically, for every set of parents. Everyone has their own values and beliefs so it is very hard to tell someone that their style of parenting is bad or incorrect. Some things, such as physical and verbal abuse, are obvious indicators of bad parents but it is not always so simple.
In My Sister's Keeper, by Jodi Picoult, the parents definitely straddle the gray line between good and bad parenting. They did everything they did because they were just trying to help their daughter overcome cancer. They clearly care about their children but they also make it seem as if Kate is their favorite. Having a favorite, or most important, child is going to destroy the other children psychologically.

Anna is forced to struggle with the internal conflict of whether her parents love her or just want to use her for Kate. The article explains how honesty and communication are the two most important things to keeping a family together but in order to have those there needs to be trust.
