Human: How do I get my son to stop fighting with his sister? Assistant: 
One way to help your son and daughter get along is to teach them how to resolve conflicts without resorting to physical violence. Encourage them to talk through their problems, express feelings and needs in a respectful manner, and compromise when possible. If they are unable to come to an agreement, it may be helpful to involve a third party who can help facilitate the conversation and provide guidance on appropriate behavior.
