I have a 13-month-old little boy that appears to have an across-the-board (i.e., auditory, oral, touch, etc.) hyposensitive form of SPD. He may also have some social, emotional and play dysfunction. I find a lot of information on this site about treatments and prognoses for hypersensitive cases, but not too much about the hyposensitive end member. Can anyone give me good advice on therapies to try? Does anyone know whether it's something that typically improves with time?
