There has been a lot of talk about this, but apparently there is not much
difference that girls are going into puperty much earlier than in the past.
The normal age for puberty for girls is 9-14 and that has not changed.  If
the puberty starts earlier, it is called precocious puberty and there is
usually a medical problem underlying the reason for going into puberty
earlier.
My daugther is 10 and just recently started her period.  She was 10 and 3
months when she started.  I was 10 and 11 months when I started,  so yes she
was earlier than me,  but not significantly earlier.
There is a whole lot on this on the web.  I copied below what one site was
saying.

Overview

Puberty is the time during which sexual and physical characteristics mature.
Precocious puberty is when these body changes happen earlier than normal.
Symptoms

In girls, precocious puberty is when any of the following develop before age
8:

   - Armpit or pubic hair
   - Beginning to grow faster
   - Breasts
   - First period (menstruation)
   - Mature outer genitals

Some evidence suggests that it may be normal for these changes to occur as
early as age 7 in Caucasian girls and age 6 in African-American girls.

In boys, precocious puberty is when any of the following develop before age
9:

   - Armpit or pubic hair
   - Growth of the testes and penis
   - Facial hair, often first on the upper lip
   - Muscle growth
   - Voice change (deepening)

Treatment

Medications can stop the release of sexual hormones. Some tumors need to be
removed with surgery.
Causes

Puberty usually begins between ages 10 and 14 for girls, and ages 12 and 16
for boys. Some African American girls may start puberty earlier, around age
9.

The exact age a child enters puberty depends on a number of factors,
including family history, nutrition, and gender.

Often there is no clear cause for precocious puberty, but some cases are due
to changes in the brain, genetic problems, or certain tumors that release
hormones. These conditions include:

   - Congenital adrenal
hyperplasia<https://health.google.com/health/ref/Congenital+adrenal+hyperplasia>
   - Disorders of the testicles, ovaries, or adrenal glands
   - Hypothalamic hamartoma
   - McCune-Albright
syndrome<https://health.google.com/health/ref/McCune-Albright+syndrome>
   - Tumors that release a hormone called hCG
