My husband and I work full time and don't have another option. My son is 3.5 and has attended daycare all his life. The last two years he has had terrible behavior at school including hitting and other physical aggressiveness to both teachers and students, yelling, tantrums, refusing to listen to the teachers, and using fresh language. The school has asked us to seek an outside observer to come into the school to evaluate his behavior and develop an action plan for them to use to help improve his behavior. I have no idea what kind of specialist I can get to do this kind of evaluation. I have spoken to psychologists, social workers, moms, teachers, etc. but haven't found anyone who will come on site. Any suggestions?
