I think. I’ve never met another stutterer in my life until now, and we didn’t meet yet. Out of the two (Or three or four) hundred kids in my school, only me and some boy has a stutter, both moderate-severe. I think it depends on the type though. I heard 84% of stutterers are mild, 24% are moderate and 1% are severe. We probably heard a mild stutter we just didn’t realize it, but never moderate or severe because of the low percentage. I’ve had kids told me I’m the only stutterer they knew.
