M.S.
My son has many similarities. He is the same age and is in the same pre-school program. Very little use of language. The problem is what they have is a language delay not speech. Most of the kids in the program have speech delays which is more about articulation rather that use of language like our kids. He is in the process of being evaluated for Sensory Processing Disorder...which we are all pretty sure he has. The frustrating thing is that he has been in early steps since 18 months old and this is the first we are hearing about it (thank god for his teacher). While we are still waiting for diagnosis and treatment I stared to the GFCF diet and biomedical treatments with tremendous results. If you want to know anything more SPD please feel free to contact me. Unfortunately there isn't as much info out there as there is on Autism and Dr's don't know much about it either
