um, not sure if you're talking about my chest or my height, but i'll answer both. i only really started growing a chest when i was about 15. it was so mortifying because every other girl had started developping about 3-4 years ahead of me...i actually heard someone in class call me a flat asian pancake in 9th grade! how terrible is that??
as for my height, i grew a lot from 15 on. i'd say 2 1/2-3 inches probably. i grew a whole inch and a half last year alone..so if you're young and not as tall as you'd like to be, don't fuss over it. puberty will save the day
