Most inhabitants go though theres young at heart, because that's one of the first signs of puberty. I know I started growing in class 5, so um I was 11?
But kids are going though that younger and younger at the moment, so this will probably be your height, sorry to utter. Average for females is um 5"4 if I'm not mistaken, so 5"3 isn't a big difference, I'm 5"3 or 5"4 (also my doctor said I'm probably still growing because I still haven't gotten my period, I know its unusual I'm almost 16, but every time I go to here (one-two months) I grow a bit more.)I don't remember and I'm fine next to it (curse short parents ;P my moms 5"0 my dads 5"6), if you don't like it theres nil really you can do about it, in that is these injections that my sister could of got because she a growth lesser amount (no shes not a midget or little person) shes 4"10 and trust me guys like it, they believe when a girl is small its cute.

(i'm 15 almost16, my sisters 18 almost 19)
You grow in your sleep, you'll get the impression joint pains really fruitless ones, when you grow.
Well, you do grow when you sleep. But too much sleep is really bad for you. Also, after puberty, you don't grow as briskly.
