Developmental reading disorder problems, so I am not qualified to address matters about the medical implications of hearing loss. However, from the behavioral perspective, it will be important to learn from the ENT doctor or your son's audiologist how much your son's hearing loss should be expected to impede normal day-to-day parent/child communication. You indicate that your son may be hearing better than he indicates at times, and this may be so. But it's best to learn from the specialists and then you'll know better how to proceed from a parenting point of view.
