Can you ask to observe? Not for 10 minutes but for an hour or two at a time of day the staff say is problematic. As his parent, who will know what he's thinking much of the time without actually having to have him spell it out in words, if you can see any of these behaviors yourself you may have much more insight than the staff of the preschool. If he doesn't hit at home or on playdates, if you haven't seen it, how are you supposed to discuss that behavior with a psychologist?
