Stupid article. I don't mind my dd dressing up as a grown up (although I wish she'd put my clothes back after she wears them!) She can experiment as much as she likes, but I'm not going to buy her mini-hooker clothes, nor do I think it is a good idea for her to be seeing them in shops. She is nine, and only one of her friends is anywhere close to starting to get an adult shape (and sadly that's because she is overweight). I would be sad if she wore much of the crap peddled towards her age group in the UK when is a teenager, let alone now. Luckily we live in somewhat more socially conservative Canada (plus this really isn't a fashionable place). In fact dd is one of very few girls to even wear skirts/dresses.
I was sexually assaulted at the age of 12 or so and I think one of the reasons is because I was very tall and looked much older than I was (of course the guy might have been particularly attracted to little girls, who knows), so I really am very sensitive to her dressing to her age and not her size (she's now wearing 12-14).
But of course I am aware of her growing up, starting to get interested in boys, developing physically etc etc. We have lots of chats about relationships, sex, puberty and whatever else takes her interest, and she is slowly changing from a little girl to a young woman. I think that's something to be celebrated, but not with trailer trash tat.
The hands down her pants thing has little to do with puberty - she's been doing that since she was a toddler (much more than ds in fact).
