I could be wrong but I almost feel like putting a 5-year old through a program is counterproductive. He doesn’t need to develop a self-conscious at such a young age. And unless the program is fun for him, he’s not gunna buy into it because what incentive does he have to buy into it? Again, he’s 5 so why would he care if he stutters? Just raise the kid to be expressive as possible and put him in a diverse array of social situations, so he’s toughened to every type of person in the world. Encourage and give him confidence and fight to be unique. And praise him for accomplishments other than speaking fluently. Then he will feel comfortable at school when the inevitable comes and he becomes self-conscious of his stuttering. I don’t think the kid cares about his stuttering. Maybe actually what you’re doing is scaring and confusing him into thinking that his stuttering is something he should be alarmed about. Which is only gunna make him try to hide his stuttering. Which then reinforces the habit of stuttering and adds secondary avoidance behaviors. Better to teach him that the social world isn’t as dangerous as the average person thinks, and that everybody has flaws/differences. Then he will want to speak. But then again, I don’t know about this program. If he’s having fun, I think that’s what matters. And if the kid is experiencing struggle while speaking, then speech techniques may be good to reduce struggle and muscle tension. But if he’s stuttering without struggle in the throat and body, then his mental health is in a good place already and he has a good basis for building good social skills without a program. Just my thoughts. Although I didn’t begin stuttering until an adult.
