It sounds like therapy has improved her fluency somewhat, so that's great! Maybe she's doing more than you realize, and it's working most of the time but you're only noticing when it's an especially tough block? If stuttering generally doesn't really bother her or affect her confidence, then it doesn't seem like there's any problem here. Alternatively if she truly is resisting speech techniques/strategies, in my experience it feels really unnatural to use them in normal conversation. Perhaps they should be reserved for more "important" moments, like public speaking? In my experience as a former 10-year-old girl, existence itself can be absolutely brutal, so the fact that she's stuttering freely is honestly so punk. You say it doesn't bother you that she stutters, so what is the issue?
