Have you asked your peditrician? My son, who is now 31 use to stutter because of being anxious and had an older brother who wouldn't let him talk and beat him in asking questions. This made him nervous and caused the stuttering. He went to some speech classes but it didnt help him. I just told him to go ahead and talk that I would listen to him and take a deep breath and go slow. I reminded him of this every time he would start to talk. He eventually out grew it but sometimes still when he gets nervous or upset about something, it will come out a little. I say take a deep breath. He also had a hearing problem, which we didnt know about, (fluid in the ears) and once tubes were put in, he talked much better also. Hope this helps.
