Most times language disorders cause problems in social behaviour, as poor eye contact, that can be trained in many different ways. We have created a model slide to help to say hello and good-bye. We play with the slides, one of us goes out of the room and plays that is arriving home and greets, or that is leaving the house and says good-bye It really works to change the images of the father and mother for real pictures. It might take a few days to make it work :) Hello Good-bye
