Has he had an actual sleep study? If not, that would probably be the best place to start and that can be performed at Medical City Dallas. Also, I would recommend an evaluation with Developmental Pediatrician, Dr. Lisa Genecov at Medical City. I'm sorry, I don't have her # at hand, but if you would like to call me Monday at ###-###-####,I can give you her information. Hope that helps!
