Is this just happening to American girls?
Adopted Indian girls in Sweden are reported to have a significantly lower menarcheal age than either the indigenous population or their upper class Indian peers growing up in India.2 We also have observed increased referrals of such children for precocious puberty; these have all been females, and were mostly adopted from India into Italian families.
Nineteen adopted girls were referred because of signs of precocious pubertal development. All came from developing countries, 15 from India. They arrived in Italy at a mean (SD) age of 4.0 (2.2) years (range 0.33 to 8 years) with evidence of chronic undernutrition. At the first visit, adoptive parents provided data about the country of origin, past medical history, and the habits and conditions of life before and after adoption. Consequently the first signs of puberty were accurately dated.
All the girls underwent hormonal investigations (gonadotrophin releasing hormone test, basal oestradiol, and androgens) and radiological imaging (cerebral computed tomography or magnetic resonance imaging and pelvic ultrasonography). Mean (SD) serum luteinising hormone after stimulation was 30.2 (20.2) IU/l (in our laboratory, a value > 5 IU/l suggests the onset of puberty). No neurological abnormality was found on radiological imaging. Sixteen subjects were diagnosed as having idiopathic precocious puberty, and three as having early puberty.
Precocious puberty in girls adopted from developing countries
The age at which pubertal changes occur has declined worldwide over the last few decades. In the Netherlands, the median age for a girl's first menstruation was 13.66years in 1955, 13.40 years in 1965, 13.28 years in 1980,and 13.15 years in 1997 . In Puerto Rico, which has the highest reported incidence of premature breast development, girls less than 2 years of age comprise the majority of precocious puberty cases . As a result of the alarming increase in incidence, Puerto Rico is home to the only world registry for the study of premature sexual development.
Nutrition, physical exercise, and weight are factors associated with the decline in age of pubertal changes. In addition to a global decline in age over time, researchers have observed specific patterns in certain populations. African-American girls tend to reach puberty earlier than other races . The use of hormone-containing hair product has been indicated as one possible factor in precocious puberty in African American girls. .

I doubt that clothing is causing little girls to menstruate.

Research: U.S. Boys Also Reaching Puberty Earlier Than In Past Years
"We analyzed data from the third National Health and Nutrition Examination Survey, which were collected in two phases between 1988 and 1994 on 2,114 boys aged 8 to 19 in this country," said Dr. Marcia Herman-Giddens, a researcher affiliated with the University of North Carolina at Chapel Hill. "We found that all three groups -- white, African-American and Mexican-American boys -- were significantly taller and heavier for their age than boys in previous studies, which is consistent with earlier puberty."

has anyone noticed that they're making diapers for older and older children now? Even for 7 y.o. They weren't doing that 10 years ago. What's up with that? It runs the opposite of the early maturing girls.

Yes, I was wrong. All cow milk contains natural bovine growth hormones. HUmans have been drinking it for eons, it doesn't cause girls to become fertile at age 4.

This is a reckless statement, but it came to mind.............
Maybe if those of us who are older die of something we were exposed to before the younger ones were born, they are growing up faster in order to reproduce sooner.
