This document discusses sibling bullying and why it is important to address. It notes that sibling bullying can have more severe consequences than other forms of bullying, such as increased depression, anxiety, and low self-esteem in the bullied child. These negative effects are exacerbated when parents do not intervene to stop the bullying behavior. The document also states that children who bully their siblings can develop issues forming relationships and exploiting others due to experiencing few consequences for their aggressive acts. Parents are encouraged to be aware of bullying behaviors between children and establish clear rules against such acts.
