When did I start stuttering: at age 3 Why didn't I outgrow it: I think because I made it into a habit to evaluate my stuttering during a block, for example anticipatory fear like "I can't breathe out or move articulators" (that leads to a block). I found an interesting [link](https://www.sclhealth.org/-/media/files/shared/services/pediatric-care/stutteringsharedpeds.pdf) and [link](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5945073/): >"Girls are more likely than boys to outgrow stuttering. In fact, three to four boys continue to stutter for every girl who stutters. Why this difference? First, it appears that during early childhood, there are innate differences between boys’ and girls’ speech and language abilities. Second, during this same period, parents, family members, and others often react to boys somewhat differently than girls. Therefore, it may be that more boys stutter than girls because of basic differences in boys’ speech and language abilities and differences in their interactions with others. " "Growth in productive syntax but not vocabulary diversity predicts likelihood of stuttering recovery among a sample of preschool-aged children (expressive grammatical maturity)" So basically, the theory is that people judge boys differently which leads to them negatively evaluating their speaking ability because of listener's judgements. Other theories that these researchers have found, are: the chance of outgrowing lowers, if one substitute words (and I assume also other secondary behavior or non-natural speech) and it states that speech errors, for example caused by a low vocabulary, speaking too fast, experiencing social anxiety or speaking 2 languages as a kid, lowers the chance for spontaneous recovery where stuttering develops into a habit. If a kid has difficulty following directions, the chance of outgrowing also lowers, according to this research. If a kid perceives that the listener doesn't understand him, for example, when a parent asks to repeat, talk slower or say 'that's great' without engaging what the kid has said, the chance of outgrowing lowers, it states.
