This behavior clearly has a compulsive quality to it, but the precise nature of it can only be determined via an evaluation with a pediatric mental health clinician. So yes, it would be prudent to arrange such an evaluation. What is the city closest to you? Also, it is not useful to adopt a punitive approach to this behavior. When you consider it, what is he doing that is wrong and deserving of punishment? While the behavior bothers you, it should not be characterized as wrong.
Thank you so much for your reply. We live about an hour from either Raleigh, Wilmington, or Greenville, NC.
The service you need can be located at North Carolina Children's Hospital in Chapel Hill (tel. 919-966-4131). Ask to be connected to the Child Mental Health or Child Psychiatry Department.
Thank you again so much for your response and the information. My son has actually been a patient at this hospital before. I will be calling them this morning. Thanks again!
