As a parent, you can take the following measures to help your children make friends:

1. Encourage your children to participate in social activities. Let your children participate in some social activities that are suitable for them, such as interest groups, sports teams, etc., so that they have the opportunity to make new friends.

2. Develop children’s social skills. Teach children how to interact with others, such as taking the initiative to say hello and expressing their thoughts and feelings.

3. Provide children with opportunities to communicate with peers. Let your children interact with other children at family gatherings, community events, and other occasions to increase their chances of meeting new friends.

4. Don’t force your children to make friends. If your child doesn't want to make friends, don't force them, as this may make them more resistant.

5. Pay attention to children’s mental health. If your child has social phobia or other psychological problems, you need to seek professional help promptly.
