The Playground Gets Even Tougher (New York Times): Mean-girl behavior, typically referred to by professionals as relational or social aggression and by terrified parents as bullying, has existed for as long as there have been ponytails to pull and notes to pass (today’s insults are texted instead). But while the calculated round of cliquishness and exclusion used to set in over fifth-grade sleepover parties, warfare increasingly permeates the early elementary school years.

Miley Cyrus' 'Who Owns My Heart?' video's too 'sexualized': Parents Television Council president (NY Daily News): The video, released Friday, shows the singer waking up in bed blindfolded with no pants on as she writhes between the silk sheets and saucily sings to the camera. She then heads off to party in glittery barely-there club gear -- with plenty of cleavage and leg on display -- before hitting the dance floor where she gets down with some older men.

Parents now learning about "spice" -- a rising alternative to smoking pot (The Baltimore Sun): The name "spice" sounds innocuous and natural enough. It's officially said to be "incense," with the packaging quick to tell users the product is "not designed for human consumption." But in fact, spice is not natural at all. It's a man-made chemical designed not for incense, but to get people high, critics say. Some convenience stores that sell it, retailers say, buy it from dealers hawking it out of their cars.

What do you think? Is Miley's video too sexy? Have your little girls been bullied by mean girls?
