We are at BIBIC with DS1. Therapist has recommended we do Johansen Sound Therapy with him as he has auditory processing disorder. We did AIT with him over Christmas and it definitely made a difference. I was under the impression that if we did AIT we didn't need to do any other form of listening therapy. I am wondering if anyone has done more than one type of listening therapy and if they felt it had an additive effect. Sorry for rushed post - am on my phone with limited mobile access.
