I agree that children are growing up too fast. They're being exposed to sex and violence at a young age (
) rather than being allowed to be innocent. Clothing designers make midriff-baring tops and short shorts in little-girl sizes - because they sell. Kids are wearing inappropriate outfits to school (which is why I support strict dress codes in schools).
I can also see the argument that a lot of adults are blurring the line between childhood and adulthood. I have been introduced to 5yo kids by my first name - I'm in my 20s but it still rankles me. I've given up my seat on the subway and had people look at me like wtf? It seems like a lot of parents want to be friends with their kids first, rather than authority figures. (Disclaimer: I am not yet a parent.)
As for clothes, I agree, if you've got it, flaunt it
but if you don't got it, don't flaunt it. If you're five years old, you don't got it. If you look like mutton dressed as lamb, you don't got it.
