Most parents try raise their children the way they think is best, loving them and giving them what they need. However, sometimes the adopted strategies fail. It’s normal, because we’re not perfect and we can’t always do things “by the book”. As long as the mistake is identified and subsequently corrected, things are under control. But there is a special category of parents, namely those who constantly apply methods that are harmful to their children, manipulate their children. We are not talking about occasional mistakes that are corrected but about behaviors that are maintained over time. It is good know that and kind of behavior that emotionally damages the child or causes trauma is toxic behavior. Similarly, children, in order to satisfy their own interests, can manipulate their parents, grandparents or other adults who can solve some or other problems for them.
