Im a junior in high school with a stutter that developed around your daughters age. I started seeing a speech pathologist on and off through elementary and middle school. Mine peaked in middle school but has gotten better since then. I actually dont really stutter anymore. I just get speech blocks where I cant get out a word. Ive actually surprisingly never been teased by anyone because of my stutter. Honestly, no one really gives a shit. One thing that you should do though, is when your daughters speech pathologist gives her some strategies to use, help your daughter practice them. I think my stutter would have gotten much easier as I got older if I would have just taken the time to practice some strategies. I think your daughter will do fine.
