Have fun making faces to uncover emotions.
Studies have shown that imitating the facial expression of another person actually helps you to feel empathy for that person. Encourage your child to practice making "feeling faces." Stop a movie or picture book at intervals and have your child make a face to show how a particular character is feeling at that point in the story.
You and your child can also create a collection of feeling faces—face photos that depict different emotions. Cut pictures of faces out of old magazines. Also take photos of your child posing and depicting different emotions. Mount the photos to posterboard to create a feelings collage or attach craft sticks to cutout pictures to create feelings puppets.
