Where is the balance?
I strongly suspect that these 'Handwriting lessons at 16 months' merely means scribbling with a wax crayon - should we not allow this? And ' Learning basic maths with rhymes' - isn't this just 'One, two, buckle my shoe'?
Just because a child is not ready at 4 years and two days doesn't mean they won't be ready 6 months later - why the urge to wait until 7?
My 4 year old starts this year, he is badgering the LIFE out of me about maths, he YEARNS for structure.
I think it is more to do with parental attitudes than the age they start school - the right tyope of pushy parent can whip their child up into a frenzy of anxiety without the help of any school.
