There is a relationship between weight and estrogen. The heavier girls (and
boys?) tend to have high estrogen in their system, which surely contributes
to early puberty.

Anectodally, my 13yo daughter is 5'1"/1.5m, ~100 pounds/45 kgm, and she is
starting to fill out. I started my cycles in Jr high, about 13yo. She was
b/f for 18mo, and we do not drink cow milk. I view her as "normal" but have
to remind her physician (and my husband's family) that it is ~normal~ for
little girls to start filling out ~13/14yo, not 8/9 as we tend to see around
here.

But it sure is difficult being the "normal" girl when all of your friends
have started their cycles...

Best wishes,
Heather "Sam" Doak

<<Do you think the early onset of puberty has any thing to do with
overweight?
There is a connection between formula feeding and obesity.  Most of the
little girls I see with earlier onset of puberty are too heavy.  The flip
side  of this is that if you are breastfed and grow normally, gain weight
normally, then you hit puberty at a "normal" time.  Feeling cynical today,
