I have a six year old son that was diagnosed at age 20 months with Autism and at 3 years of age with Apraxia. I am trying to find some research that would indicate what the optimal amount of speech therapy for an Apraxic/Autistic child might be. Has anyone found at what point, additional speech therapy provides diminishing returns? I am pushing for 2 hours a day, broken down into a 1 hour initial session that combines PROMPT with RDI, and then 3 additional 20 minute speech sessions. Any thoughts?
