Parents can teach good manners to their children by modeling polite behavior in their own interactions and consistently reinforcing the importance of etiquette. Engaging children in discussions about the value of good manners and explaining how they affect relationships can help them understand their significance. Additionally, parents can create opportunities for practice by encouraging children to use polite language, share, and take turns during playtime. Positive reinforcement, such as praising children when they exhibit good manners, can also motivate them to continue these behaviors. By instilling good manners from a young age, parents can help their children develop into respectful and considerate individuals.
