Family conflict can have a few distinct causes. Sometimes, an event changes the dynamic of the family, leading to conflicts. Changes like divorce, death, a new child, moving, or changes in employment can lead to conflict. Many times, these conflicts stem from a lack of communication or empathy from one or more parties. When it's difficult for one person to see and understand another's viewpoint, they may develop hurt feelings or resentment, or misinterpret another family member's words or actions. And when families can't work together or understand each other, even little things like clothing put away in the wrong spot can lead to huge blowups.
All families experience conflict, no matter how much they love each other and how well they communicate. Conflict isn't a sign of a bad family dynamic, as long as the conflict is handled properly and all members of the family feel they can speak their minds safely. It is only after communications begin to break down that the problems become more severe.
