I think this is part of a bigger picture of the constant pressure that our children are being put under by schools and society in general. I recommend reading Carl Honore's book 'Under Pressure' which gives in insightful view on this whole business.
Also, if anyone fancies doing a guest post at my blog on your views on the pressures our children are being put under by schools and the Government please contact me. I think there is a real debate to have about this!!
