Can we please take this article with a pinch of salt? No birthday parties/sleep overs etc...they are trying to sell newspapers.
I was brought up by pushy parents (one being Singaporean, the other a born-and-bred Londoner) and I was smacked, struck with a ruler, in tears doing extra maths, etc, etc...I will do the exact same to my kids.
As a child I wouldn't want to have extra maths teaching from my mother, but I never thought 'OMG, this is child abuse!' It was very obvious that the pushy attitude was for MY own good.
As an adult, I thank my parents immensely for doing with me as they did. Western children are lazy in comparison - the look of envy on the faces of other mothers was obvious to me even as a schoolgirl.
If I want to do it to my children, wasn't that abusive and damaging was it?
P.S. As for stemming creativity...I took read English at university and am now at law school. I wouldn't say I was damaged goods.
