I am a detention officer with Juveniles. The harshest form of discipline we can administer is to send a youth to his room, then we counsel the youth. Youth go to their rooms from 1 hour to 5 days depending on the infraction. I dont see why this would not work when raising your own child.
People may want to hit their children because they dont want to spend the time of sending them to their room and counselling them.
If a youth is out of control we do take them to the ground and handcuff them and then place them in a room.
When I raised my son, I didnt spank him. He turned out well he has a college degree and is a Registered Nurse. And he visits and tells me he loves me all the time.
With young youth at the jail, when we put them in their rooms they bang and cry. I guess a parent would be tempted to spank the child to stop the banging and crying, we cant do that. Very often I can stop them from banging and crying by talking and reasoning with them. If they havent got them selves locked up for 3 days, I will say young man, if you will behave and stop crying and nocking you will be able to come out of your room in a couple of hours. But if not you will have to be in your room all day tomorrow. I had 9 young men locked up on Monday and I didnt have any crying or knocking.
