Why does a twelve year old have big breasts?

Answer 1

hey im 11 and around my nipples hurt and get big huge lumps surrounding the whole nipple. and they take turns doing this but right now my right boobis slightley bigger than my left because it has switched to the right boob. it is all part ofo puberty and its fine by tommorrow mine will be the same size. plus im not even in a bra yet. so dont push the bra until the nipples start showing because i think that if u dont wear a bra ur boobs will grow faster. oh and just like me u might be getting vaginal hairs or hairs down there. completely normal two. its also normal for you to get ur period 2 to 2 and a half years after ur breasts begin to grow. but times vary LARGELY.

Answer 2

At the age of 12 you are just in the beginning of puberty, it lasts until you are around 18. They will come, trust me.

Answer 3

Don't worry about it. I'm 12, my breasts aren't developed either. :) -Lauren <3

People grow their breasts at different paces and times. It's different for everyone.
