we tried everything with our daughter. dont despair. patience and moral support is the key. there's no silver bullet fix. She's in college now and were going to try the McGuire program. You could try the SpeechEasy device. It worked for us for a bit but not a long term fix but its worth the try. It's a journey and everyone is different. you don't know whats going to work. We just keep trying. As long as they are happy and surrounded by good supportive friends and family. Good luck and feel free to reach out.
