Thankyou and I feel the same but yes she said that my granddaughter is acting out in school aggresively toward other children and not getting along, following rules in the class sort of thing. It is hard to say because I only get pieces of info and dont even know if I am told the whole story.
It would not be reasonable to assert that a single behavior is indicative of either of those things. The single behavior has to be considered in the context of the child's overall development and functioning.
