Siblings (twins specifically) and stuttering

Siblings (twins specifically) and stuttering Hello everyone, I (23m) am glad to have found this sub. My twin sister and I were both sent to speech therapy class together around 2nd grade and I specifically remember this being the time where my stuttering took a turn for the worse. The interesting thing here is the same thing happened with her. We both had big trouble with stuttering throughout the years, but since I've gone to uni and took a teaching job, I've gotten through the debilitating aspects while my sister.. has not. Obviously this is a testament to the ways that different lives can lead to different outcomes in terms of fluency, but I'm wondering mostly if any of you have had anything similar happen within your own immediate family. **Did you have any stuttering siblings or parents, or were you the only one?**
