my daughter has become tough nut to crack,hitting me n her father more of me ,cracking everything ...shouting ....gentle parenting failed...what to do?

A. Then don’t do gentle parenting do regular parenting as with what you are brought up with because i understand a gentle parenting has become so common these days that parents are ready to accept nonsense from the kids also so sometimes you need to be more strict and form and you need to show them that if we can be good to you you can also see the other side of the parents when you misbehave
