Its she stole all the potential from their mom

But she's not even blood-related to them. She's Anyd's sister through adoption.

Shit happens. I don’t want to admit, but I was a ten year old with boobs

So having a boob as a ten year old girl is possible? Sorry even now my chest is flat as an iron board. So my understanding on how boob grow are limited

same. My startet growing after i turned 19. still can't boast about them tho.

They can grow at any age between when you start puberty to when you’re in your early twenties. Mine personally began growing when I was ten (purely due to being a fat kid), but mine truly began growing when I was 12. The size has mainly to do with genetics and some part is diet and type of life.
