32A or 34A would be average bra size for a 12 year old girl.

There is no average since each girl/woman is different and breast size is based on DNA.
I think that a 16 year old girl's breast areola size should be around a size 16
It hard to say but i would say around 32 -36
That depends on the size of the girls breast and chest measurments.
There is no age-chart for breast size.
The average shoe size for a 2 year old girl is a US size 8. This size is in Adult size.
There isn't actually a 'normal breast size' because everyone is different.
