Just around the time when a girl is to reach her puberty, her breasts start to develop signalling that your daughter is finally not a kid anymore. From the age of 8 to twelve, they would be no more than a nipple elevation which would be followed by budding as the days pass.
In some, this budding, that might start at the age of 13, which is actually the formation of the breast bud, might start earlier as well.
And as your daughter grows up, it becomes necessary for her to start wearing her first bra which is necessary since they would keep her breast in shape and also ensure that the growth is linear throughout.
