If you think your daughter hit puberty way too early, you're not alone.
About 15% of American girls now begin puberty by age 7, according to a study of 1,239 girls published last year in "Pediatrics." One in 10 white girls begins developing breasts by age 7 -- twice the number seen in a 1997 study, reports USA Today.
There are some dangers involved. Early puberty increases a girl's chances of depression, drinking, drug use, eating disorders, behavioral problems and attempted suicide, according an earlier report.
Why is this happening? Researchers say the following may be contributing to the phenomenon: obesity, prematurity, genetics, too much TV time, family stress and environmental chemicals.
