Mr. mm and I went to a church where a wonderful, godly man was a PhD in psychology. We were discussing girls going into early puberty once and he said that a lot had to do with early exposure to sexual materials and culture. Some cultures that were sexually *freer* have much earlier onset of puberty in girls.
Seems like that early exposure actually can trigger it physically.
As our culture is becoming more sexualized and kids are being exposed to not only sex, but sexual perversions, it takes it’s toll in many ways and it’s no surprise that girls would be starting puberty earlier.
