Hi! I was the exact same way. I kind of knew I had a stutter but I wasn't fully aware of it. I would suggest you bring it up next time she has a stutter where you can see her really physically struggling with it. Let her finish speaking and respond to her of course, but for me, that's when it would click a little that I had trouble speaking because I would be so out of breath. However, I wasn't sure what was happening because nobody talked to me about it. Just assure her that there is nothing wrong with stuttering and it might be something that may or may not ever go away, but that the friendly therapist can teach her helpful ways to make speaking easier for her. Once she's older, I'm sure she'll be grateful that you started taking her to speech therapy.
