L.-- does your son have any difficulty with social situations, like making friends or going to birthday parties? I ask because that can be a sign of Asperger's syndrome, which is a high-functioning form of autism. I hope I'm not scaring you; I'm not a doctor, but I have a son with autism, and Asperger's seems to run in our family. I would recommend that you ask you ask your pediatrician for a referral to a developmental pediatrician to discuss your concerns. That way if he does have Asperger's, he can get some help with social functioning. If he seems just fine in social situations, then I highly doubt it's Asperger's, and it may just be that he has some sensory issues, like sensitivity to sound. That may account for the "spaciness"-- some kids with sensory issues will "zone out" for a time when their senses are overloaded by a lob of stimuli. I would highly recommend a book about sensory issues callled The Out-of-Sync Child. (sorry-- can't think of the author, but you can google it.) It's a book about Sensory Processsing Disorder, which is just a fancy way of saying that some children (people) have trouble processing the information they get through their senses. There are different types of sensory difficulties, which may affect the senses of sight, sound, touch, taste, smell, and some fancy ones like vestibular, which may affect balance. Your son may be covering his ears because of a sensory issue with sound. Again, I'm not a doctor, but as the mother of a child with autism, I would recommend an evaluation just to rule it out. I really don't mean to scare you; I just know that kids with sensory issues and/or Asperger's can really benefit from therapies, so I think it's better to find out for sure so that your son can get help if he needs it. By the way, if I didn't make this clear, your son may have some sensory sensitivities and NOT have Asperger's; they can exist independently of each other. The hallmark of Asperger's tends to be a difficulty with social situations-- difficulty making friends and coping with birthday parties, preferring to play alone, etc. Feel free to e-mail me if you have any questions: ____@____.com this wasn't too much info!! ~B.
