As someone who was in your child’s place, please stop doing this. My parents were the same way. Very kind and supportive but they always kept saying things to use my therapy stuff or slow down or breathe etc no matter how much I asked them to stop. This is my personal experience, so I can’t speak on how your daughter feels but my parents doing that made me hate the way I talked because it kept being brought to attention even in public around other people. It was frustrating when I would use my strategies and still stutter. For a while if I started to stutter even with using the therapy stuff, I’d stop talking in the middle of my sentence because I didn’t want to keep hearing my parents bring it up. Again, this is my personal experience but I wish my parents didn’t keep saying those things to me. It was never malicious or rude, it was always loving with the best intention but it didn’t accomplish what they hoped for it to. It’s been 10 years since I was in therapy and I use all the stuff I learned maybe 50% of time when I want to/need to in specific situations. Rest of the time I don’t try to stop it. If she doesn’t want to, don’t make her. If she wants to then she has the knowledge to do so. Let her make her choices on how she chooses to communicate.
