I also have done that. For example, I blink hard when I stutter. Idk if that makes sense :). I wouldn't worry about it. That kind of subsides after some time. I have also had good times and bad times with my stutter. Some months (particularly summer for some reason) I can barely talk, while other months, I am like everybody else. The best thing you can do is remind her to use her strategies that they are teaching in school for about 10-15 minutes a day (Not the whole day). Also set a specific time to use strategies, for example after dinner. Also remind her that you can be very successful even with your stutter. For example, Joe Biden, Winston Churchill, King George the 6th, James Earl Jones, Elon Musk etc. Good Luck and Stay Safe
