Please please please take your child to a pediatric neurodoc -- pediatric neuropsychiatrist for choice. There are about a dozen things this could"be".... including, as mentioned above, protest at being over-stimulated, which likewise might or might not be indicative of a developmental syndrome (such as PDD or Aspergers or others). Having it checked will give you peace of mind as well as potentially very valuable clues as to what's going on with your lil guy. Best of luck! Chyia, crossing fingers
