text: Unfortunately I was one of those poor girls in school who was blessed with C cups at a young age.  Actually when I left 6th grade I was like a 32C.  Along with that a females period begins...I think it has something to do with the larger mammory glands.  My daughter is the same way, and I just talked to her and told her what to expect.  You have to guide her thru highschool.....because the kids now are relentless.  Really have to be there for her.
