I would definately stay in one place to get assistance with your language delayed child. My grandson also had that and was enrolled at age 4 in a program thru the schools that allowed him to be with other children with various learning challenges. This helped him immensely and by the time he was 5 he had partial speech, still difficult, but had stopped making noises when trying to express himself and tried to use speech intead. By age 7 he had good speech patterns. I do believe his early intervention programs were responsible for his improvements. They actually recommend that they be started by age 3. I don't know if this will be the case with your child or not, but at a later age our grandson was diagnosed as ADHD and mild autism. This has created challenges for him with his behavior. Getting your child on track as far as speech should be the first concern. The longer he challenged, the harder it will be for him to overcome this problem and it definately affects how he can socialize with other kids. Very important for him to be able to make friends.
