Hi, unfortunately he has not. He sees a speech therapist every week but it doesn't really make a difference. He does stutter less... Either that or we just got used to it ha! No i think it has gotten better, mostly imo due to our modified behavior towards him and his stuttering. Right now his stuttering is just a little bit worse than average 3-4 year old stuttering (many people like his teachers friends and family say they didn't notice). His stuttering really gets worse when he is tired though. Really we're just being patient and calm... To tell the truth we're having problems with our younger son... Developmental and speech delay... Autism suspected. So it's been really hard but it puts things in perspective. At first my eldests stuttering was the end of the world to me, but now it seems so minor. All we can do for both kids (other than taking all the measures and seeing all the doctors and experts we can) is just living in the moment and enjoying their childhood... It's great!
