Is it weird if a girl's body developed at very early age ??

In fact no, it's actually a lot more widespread than you think XD. Mine started when I was in the fifth grade, when I was 10 lol. I've heard people say that it's becoming more and more common too due to plastic products.

I think girls are developing earlier nowadays . My youngest is 11 and she’s already starting

Kinda becoming the norm.

Which as a parent, really really sucks.

I think its weird, yes. But it happens.

It's not weird some girls develop faster then others and at a young age, some as young as 8.

Most of the woman in my life began developing breasts around 8yo.

I've seen it before

Early onset Puberty was rare when i was a kid ('74) but these days it's not so.
Endocrinologists are still arguing over the cause.

it happens and unfortunately there are cases of very young age and some of hte youngest pregnancies :/

Statistically unusual.
And prbably complicated

Not fair yet true
