I research stuttering for one of my classes, and here’s what my studies have found People tend to grow out of stuttering at around their own respected teenage years, and even then so you slowly begin just gaining fluency skills and throughout the years it becomes second nature almost Also coming from someone who also stutters himself…I’ve stuttered I’m pretty sure my whole life, and I think that’s why I came to this Reddit, subreddit whatever. I digress. I’ve kinda just grown out of it, I still stutter here and there but people who I meet and then I tell them months later are genuinely shocked that I have a stutter, and think it’s again all just a psychological game, you just have to take the reins and obtain fluency tips. Does that help your observation?
