Ok, is this conventional or not...?
Answers: Little sister? Shouldn't you know if it's normal? It is. It could be an allergic hostile response, but it's probably something called growing up/puberty..
Maybe if she is wearing a bra, she might be allergic or having a impulse to the material in it.
Other than the itchyness, i never experienced that.
Emily..
Oh this happen to most of people during puberty both males and females. Nipples feels bloody and some people experience also a pain contained by the armpit.
It goes away with time. Don't verbs about it.
:).
yes its normal . i remember that age . its no fun .. the principle her beast and nipples are itchy is becuase they are growing and stretch marks might be trying to appear . theres cream for that at the store to comfort ... I have several vague memories of some bizarre sensations surrounded by my nipples throughout my prepubescent years. Itchiness included. If she's really concerned get a breast scan just contained by case..
It could be that she is allergic to a shirt or bra that she is wearing. But if not, it is regular when developing. xox totally normal.
I experienced it too.
And I'm a male. Normal, Chill.
It is average are you sure this story isn't about you?
