I simple don't approve of any type beating / spanking to teach a child a lesson. Here it's such a common thing. Parents beat up thier kids for minor mistakes, without warning or even trying to rectify it. It is also a common means of taking out the frustration from their daily lives. Children are so vulnerable and can't do anything against their parents, that often a minor mistake is taken as if a big crime has been commited and that nothing less than severe beating will do.
This does a lot of long term harm. I remember a friend of mine having such parents, and I can tell you, how underconfident she is, she can't argue, even if she is right she will just resign to the other persons views, she gets nervous very easily, and she is so afraid to voice her opinion lest she offended someone. She is a very beautiful (as in the inner beauty) person, but just look at what all the years of such treatment did to her. Her parents think that what they have is a disciplined child, but, I don't think so. I mean she isn't indisciplined, but the way she is.....is quite hopeless.
It is so important to deal with children properly, and parents should take advantage of the experience and their own life to analyse the situation. But spanking / beating is just not done !
I remember one incident she narrated -- She was very small, and like me, she too is not so fond of Maths. So, here one day her father decided to teach her some division. He taught her for a while, gave he some sums to solve, while she was trying to do it, he dozed off. When he woke up, he finds that she couldn't do it / did it wrong. This made him so angry that he just threw her off the bed, then the beatings began as to how bad she is, she can't learn a thing and all...She calls for her mother, she comes, but just stands there, and she too is saying to him that yeah she deserves it, do it some more

. She was then left alone, and then for quite sometime no one talked to her, making her feel as if she is a disaster, and that not being able to solve certain sums is a hugely wrong thing to do.
When I heard of this, I was like...WHAT??!!!
She as a child then was so confused, she didnt know what did she do so wrong that she had to be beaten up like that.
I was so enraged
I simple don't approve of such a treatment. Because, it not only does physical harm, it has emotional consequences too.
