There could be a variety of reasons why your child is fighting at school. It is important to address the issue and try to understand the underlying cause. Some possible reasons may include difficulty with social interactions, difficulty managing emotions or frustration, or a problem at home that is affecting their behavior. It would be best to speak with your child’s teacher and/or school counselor to gain more insight into the situation and to develop a plan to address the behavior. Additionally, you may want to consider seeking the help of a child therapist or counselor to work with your child and address any underlying issues that may be contributing to the behavior.
