I started to notice that explaining things to my 6 year old daughter doesn't help much. I mean not at all. No matter if i explain to her that she hurts somebody else with her actions or if she can hurt herself, nothing seems to make sense to her. the only thing that works is the reward chart, black dot, pink star. And i get worried, since at 6 years old she should be able to undersatnd she is not alone in thwe world. What shall i do?
