One of the things that bothered Lyn Mikel Brown and Sharon Lamb most when they researched Packaging Girlhood was the erosion of the boundary between childhood and adolescence. It's not only that little girls are introduced to a teen lifestyle earlier and earlier, it's that the definition of teen has become almost completely narrowed to hot, shopping girlie types -- as if this is the only way girls can look and feel grown up. Forget their maturing minds and moral sensibilities, their skill on the playing fields, their passion for theater, art, or science and just give us sexy. Why? Because if you can channel that wide-eyed desire to look cool and mature in your direction, there's money to be made. The health, well-being, and safety of girls be damned. Enter Beyonce and her mom, Tina Knowles, and you have the new "House of Dereon" little girls line of clothing designed to make your 6 year old the coolest girl on the urban street corner.
