3.5 year old daughter stuttering for 6 months now

3.5 year old daughter stuttering for 6 months now My 3.5 year old daughter has been stuttering for at least 6 months now. Last week we noticed her stutter became less frequent and we started feeling really good about it. Then, over the past week, her stutter got significantly worse. She doesn’t get frustrated, lock up or give up when talking. She does, however, have instances where she will have up to 9 repetitions at a time. Overall, the stuttering doesn’t seem to bother her nor does it really seem like she notices. We have been working with a speech therapist for the past month, which has been a huge help in navigating this. I’m just seeking advice or stories of others who may have gone through a similar experience and how things have progressed.
