I don't think it is abuse. I wouldn't make my child stand on a corner with a sign. I certainly don't hesitate to make them feel ashamed when their behavior warrents it. IMO, the possiblity of shame (feeling ashamed) can be a great tool. That and fear of my Mom kept me on the straight and narrow.
This is creative discipline - do you really think a child is going to be scarred for life by this??? PUH-LEASE. Our children now live in a society where anything and everything you do could be posted for the entire world to see and discuss - better get them ready for it early people. It's not like it was when most of us where growing up - times they are a-changin!
Parents embarrass their children all the time time - although most often its probably unintentionally - lol! Many of you probably think you haven't - or you never will, yeah....you're probably right. :)
It's not abuse . Embarrassing as all hell but I don't think shaming is a bad thing. My mom would tell my aunt and grandma about my bad behavior and I would think wow your just throwing me under the bus. I didn't redo the bad behavior though. That lil girl is lucky all she had to do was hold a sign after bringing boys into her parents home. Parents are trying to find ways that are effective and not phyisically harming them and this seems like a good way.
I personally think that discipline should be soley between the parents and the child. You have to start expecting and rewarding good behavior from the time they are toddlers. You can't suddenly start when they are teenagers.
I think its a case by case basis. I wouldn't make my child stand on a street corner for being mouthy. But if I found out he was in some way humiliating another child he would publicly apologize to that child which probably would be a little embarrassing for him.
