My DS was much the same. He is still a bit behind in his speech but the one thing that helped him the most was a CD full of kids songs. We played it every time we went in the car and sometimes, just as background noise at home. Within weeks there was a remarkable change in his speech. There isn't actualy anything wrong with my boy, we are mainly just a quiet family so that is why he is behind. If you are really worried that something is actually wrong, definately get him checked out. They tell you off more for not going in than for going in and finding nothing wrong (as I found out recently lol). Oh aqnd he also just didn't want to listen to me when I called him grr. HTH
