Girl, you'll be a woman sooner than expected
Puberty is arriving ever younger in American females -- 8 is no longer considered abnormal.

AT 8 or 9 years old, the typical American schoolgirl is perfecting her cursive handwriting style. She's picking out nouns, verbs, adjectives and adverbs in sentences, memorizing multiplication tables and learning to read a thermometer.
She's a little girl with a lot to learn.
And yet, in increasing numbers, when girls this age run across the playground in T-shirts, there is undeniable evidence that their bodies are blossoming. The first visible sign of puberty, breast budding, is arriving ever earlier in American girls.
Some parents and activists suspect environmental chemicals. Most pediatricians and endocrinologists say that, though they have suspicions about the environment, the only scientific evidence points to the obesity epidemic. What's clear, however, is that the elements of female maturity increasingly are spacing themselves out over months, even years -- and no one quite knows why.......
The new "8" -- the medically suggested definition for abnormally early breast development -- is, the society says, 7 for white girls and 6 for African American girls.
The lack of adequate explanation has some experts worried. "Over the course of a few decades, the childhoods of U.S. girls have been significantly shortened," Steingraber says.
Redefining 'average'
The new average age of puberty, some fear, may be like the new average weight -- typical, but terrible.
Time for a talk
What's clear is that physical appearance is getting ahead of other aspects of girls' maturity. They might be perceived as far older than they are, even when they're still rummaging through their mothers' closets to clomp around in oversized high heels.
"My daughter started developing breasts maybe around age 8," says Rhonda Sykes of Inglewood. "She was still into her doll phase and dressing up to play." So Sykes began having frank mother-daughter conversations about curves and changing bodies a bit earlier than she expected.
"Whatever they look like, they know nothing," says Diana Zuckerman, president of the National Research Center for Women and Families. "Eight- and 9-year olds are learning to make change for a dollar. These are children who are learning the most fundamental facts in school. Imagine trying to teach that child the fundamentals of sex. They're not even playing Monopoly yet. They're still playing Candyland."
The medical community calls earlier puberty normal, the trend goes hand in hand with the obesity epidemic, and science has not yet pinpointed the reasons. And yet, when girls who are still children in the minds of their parents start developing breasts, many of their mothers remember that it happened later in their own lives -- and wonder why.
