He does repetition with the first sound a word, usually the first word of a sentence. When it's really bad, it's nearly every word of the sentence. It first began years ago, I think he was about 7 at the time maybe? His was after a strep throat infection (PANDAS syndrome.) BUT, I've been told that the thiamine protocol works for many types of stuttering and causes. It really is heartbreaking, I'm sorry you're going through that, hopefully you can find something that works for your child. ❤️
