Your child may not understand the social norms and rules that come more naturally to other children. Provide clear explanations of why certain behaviors are expected, and teach rules for those behaviors.
Encourage your child to learn how to interact with people and what to do when spoken to, and explain why it is important. Give lots of praise, especially when he or she uses a social skill without prompting.
Practice activities, such as games or question-and-answer sessions, that call for taking turns or putting yourself in the other person's place.
Help your child understand others' feelings by role-playing and watching and discussing human behaviors seen in movies or on television. Provide a model for your child by telling him or her about your own feelings and reactions to those feelings.
Teach your child how to read and respond appropriately to social cues. Give him or her "stock" phrases to use in various social situations, such as when being introduced. You can also teach your child how to interact by role-playing.
Foster involvement with others, especially if your child tends to be a loner.
Teach your child about public and private places, so that he or she learns what is appropriate in both circumstances. For example, hugging may not be appropriate at school but is usually fine at home.
