Why are some people systematically assuming that because a kid is being competitive to the point of being sick, it is forcibly because they are unhealthily pushed by their arrogant parents who are just expressing their own failed success on to the their kids?
Why not accept that kids are not just the extension of their parents, and develop their own personalities too? It is a scientific fact (as I learned when studying psychology at Uni) that personality traits are also to some extent genetic, so some children will born with it.
As said, DD is wired that way. She would be miserable if she didn't evolve in an environment where she is challenged. Probably something to do with me because I'm like that too, but I didn't have pushy parents at all, more the opposite, I wish they had challenged me more, and I am not pushing her either. Indeed, DS is not wired this way. There is a part of him that can be competitive, but it's nothing like DD, totally different personalities. I don't expect him in any way to be like his sister. He is his own person and has his own qualities.
I accept my kids as they are, both of them, so who is to judge that if my DD is competitive, it has to be because I'm a pushy parent (which I've been accused of a few times because just some posters here, it's been assumed that I must be if my DD is so determined to succeed).
