When training for being a speech path, you get overall training for all ages and all disorders. Then you tend to specialize-kids or adults and for various environments (schools, hospitals, nursing homes, etc).
As far as too old, no, any age child is fine. I worked with kids from preschool to high school (school district). It is more common to work with younger kids but all ages are worked with. So, simple home, I would definitely have my 11 year old tested if you think it would be worthwhile. (that is actually still elementary school age : ).
momto2blessings: why don’t you do both? Try the slower speech at home having everyone work on it. It may be easiest to have a “set” time to do so (like during narrations or meals or ???). That way you don’t feel overwhelmed by trying to do it all the time. And set up an eval too. I’m thinking that the speech path didn’t hear any dysfluencies while you were in her office. So you may want to transcribe (basically write down EXACLTLY what your child has said with the exact number of dysfluencies and any other behaviors you noticed-like tension, eye closing or blinking that is not normal, etc) or even make a tape or video of them so they can see them even if they are not present that day.
Occasional dysfluencies are normal for everyone (more so in young children as they are learning language and learning many other things). These are usually repetitions of words or phrases (occasion sounds/syllables). They can increase with illness, stress, etc.
True “stuttering” is characterized by multiple dysfluencies. They usually get worse (both in amount and tension). These are usually repetitions of sounds and syllables, sometimes with “stops” between repetitions (stops are filled with tension of the mouth and face). The child becomes self conscious of it and that makes it worse also. These can also be made worse with illness, stress, etc but there is a marked difference from “normal” dysfluencies and they do NOT disappear once the illness or stress is gone although they may lessen slightly.
If I can help more, let me know.
