Do you look at your little girls and think "they're growing up too fast"?
Well, the American Academy of Pediatrics says you are right. Girls today are hitting puberty earlier than ever before, some as young as 8 years old.
"I think body weight has a lot to do with why we're seeing girls have periods earlier and see girls mature earlier. We know that the more fat cells a girl has, the more likely they are to have excess estrogen," says Dr. Sujatha Reddy, OB/GYN.
Dr. Reddy says that may be why girls today start their periods on average by age 12, compared to the average age of almost 15 in the late 1800's. She says aside from weight gain, environmental toxins may also be a factor.
