Remind her that it’s OK to stutter. It doesn’t make you less of a person. That’s one of the biggest things imo. You can’t control other people being assholes, but you can support her by not interrupting her or treating it like it’s some disease. Stuttering will probably be a lifelong thing, and don’t get anybody’s hopes up by suggesting otherwise. My mom did the exact opposite as everything I mentioned, and my life is much worse for it. With that said, seek therapy, but not at her school. School therapy, at least for me, was a once every couple months thing and that wasn’t helpful at all. Speech therapy in general wasn’t that great for me, but it works for a lot of people. My stutter comes and goes in waves. It was worse in high school but now at 22 I’m doing a little better. I’m probably due for another wave lol. The main thing though is helping her build her confidence. People are gonna be rude, even in adulthood. So it’s important to build that foundation now so she doesn’t end up with low self esteem like me. There’s probably something else I forgot to mention but it’s ok. You’re already on the right path by coming here and asking for advice on how to support your daughter. Best of luck to you both 💖
