"Violence in, violence out"

I've just read that once violence goes in, it comes right out. There is no doubt that when children are managed by using the threat of violence, punishment, or guilt, they will resort to violence, punishment, or guilt when they feel out of control as a way to regain control. Without a new way of managing and controlling children, they will become increasingly violent and continue to behave in dysfunctional ways. Either they will act out in rebellious and aggressive ways, or they will turn that violence inward and abuse themselves with low self-esteem. Either they hate others or they hate themselves, and often feel both.

I am recommending  Children are from Heaven by J. Gray, I tell you it's a nice read for mothers like me....or to all parents.
