I was hoping for some specific advice on DS's social skill. DS's (turned 4 3 weeks ago) speech is pretty good, at least he communicates his needs well, he tells us what he wants to eat, when he wants to go out etc, so it's pretty much now trying to teach him social skills, and how to continue with conversation. One thing really stopping him progressing at the moment is not understanding social cues, for example if somebody says to him 'bye DS', he will just repeat 'bye DS'. Today DD hit him with the phone and I tried to get her to day 'sorry DS', she would not say it but he kept repeating 'sorry DS'. I don't know how to get him to respond to this very basic social skills appropriately. He does understand the concept of people having different names, so when he sees picture of somebody he will say their name. I can't work out why he thinks he has to repeat? I have seen him over and over saying proper good bye to his toys (all the teletubbies, dora etc) when he is leaving them for some reason.
