1. Enhance communication environment: Create a warm and stress free family atmosphere, encourage him to share daily trivialities or feelings. Choose a topic that interests him as a starting point and gradually guide him to participate in the discussion. Set up a family "sharing moment" where each person takes turns telling the little things of the day, making them feel respected and expected.
2. Provide support and understanding: Show acceptance and understanding of his personality, avoiding forcing him to change. When he is willing to speak, give positive feedback and listen without interruption or criticism. Encourage him to express himself through other means, such as writing, painting, or participating in interest groups.
3. Participate in social activities together: Invite him to small, comfortable social gatherings and gradually expand his social circle. Notify him of the details of the party in advance, so that he is mentally prepared and can choose whether to participate or not. At the gathering, provide him with appropriate companionship and support to help him gradually adapt and integrate.
