Your son's behavior is unusual for his age. You might consider an evaluation with a pediatric mental health clincian for the purpose of gauging his overall status in the various domains of development. A developmental pediatrician could also provide the assessment.
Thanks Kevin! will do s soon.
However, I would prefer to observe him for a little while to gauge if its his real feelings or he is quoting someone else. Because in school is mostly in interaction with 8-9 years old kids!!!
