i dont think big at all? probably none, like my nine year old sister. i dont think i got breasts until i was 11 or 12!
I am a 11 year old girl and I have no boobs. So really the average size is none. I only have breast buds.
34
32A or 34A would be average bra size for a 12 year old girl.
Breast size varies greatly among individuals, so there is no definitive average breast size for an 18-year-old. Factors such as genetics, body weight, and hormonal influences can all impact breast size. It is important to remember that everyone's body is unique and there is no standard or "normal" breast size.
34B
b or c
1 cm
Its depend upon their body type..
The average breast size would probably be a B. but everyone's different . People start puberty before others do, and some people grow faster.
The average size is a 32 A or 34 A but if you are bigger or smaller its just how your body is growing
Between the ages of 10-12 the average size of a male brain is 1,440 grams and the average size of a female brain is 1,260 grams. The size of a nine year olds brain is only slightly smaller.
Id say anywhere from 30A-36B
