These aren’t new. I have a friend whose daughter was 11 or 12, 3 years ago and she bought her a padded bikini.
I noticed right away as I we frequently have dinner together and I thought “She didn’t blossom overnight”.
I had another friend insist I was not looking at a mirage and I said “Don’t be ridiculous and try to insult my intelligence or pull a houdini on my eyes. She ain’t that endowed and it’s stoopid to have a 12 year old acting like she’s a 20 year old.”
But hey, that’s just me.
I’ve a cousin, my cousins daughter, who when she was 13, didn’t need a padded bikini. She had bigger boobs than her mother.
13 yo girls didn’t look like that when I was 13. Gotta be those hormones in the water and milk and stuff.
