Homeschooling with Auditory Processing Disorder

We suspect that our six year old, Brian has auditory processing disorder. This means he cannot hear and process information easily. Our speech therapist noticed this, because she does what is called speech babble with Daniel to work on his language. She'll say bee bop bay (or a million other combinations) and Daniel has to repeat it. When Brian sits with us to help Daniel, she'll ask him to repeat the babble first to help Daniel understand what to do. He cannot repeat it. So our speech therapist recommended Earobics. This is just a simple game that builds the child's auditory processing skills. Brian's favorite game is a drummer that plays his drum and you have to count the number of beats and then repeat it. Right now we are focusing on his hearing and vision before we stress the academics. If he can't hear or see well, how can he learn?
