Depending on the girl and when she started puberty (if at all by age 12), her breasts will probably reflect that. At 12, many girls will be roughly an A- or a B-Cup. Some girls may be larger, and some may be smaller. There really is no "normal" sizeing scale to go by.
There is none. What size you'll have depends on your genes.
If you are 11 or 12+, then you may be going through puberty. The increase in gonad size and the breast size is a sign.
Well there is not an accurate bra size because everyone is different but, my cousin started puberty at 9 and she wears a C cup at age 12
There is nothing you can but wait for puberty. If puberty is over you can ask your doctor for help but surgery is the only way then.
Well you should be about done at 15. If your breasts do grow any more it shouldn't be much. I had the same size breasts all through puberty and up till I was 17 and I started taking birth control pills and that increased my breast size by two cup sizes.
No because your breast develop during puberty at it will take a good few years of developing to get that size
buds at the beginning of puberty is a slight bump that's hard and may be sore
yes but you don't have to worry about what time you do sex anyway when the breast become very big what are you going to do Girl's breasts increase in size during puberty just as boy's penises also increase in size during puberty. Girls breast do not increase in size during sex, they are not inflatible.
The average breast size would probably be a B. but everyone's different . People start puberty before others do, and some people grow faster.
Discharge is linked to puberty and not breast size. Discharge is what cleans the vagina.
This all depends on how far into puberty they are. It could be 1.5 inch if puberty not started.
It's different for each girl. For a girl who has hit puberty and has been experiencing it for long it is normal for them to be from a cup size AA-D but it all depends on the DNA and family history.
