Where ?: You get the most from this site when you provide detailed information followed by a clear question. At nine, your girl may have a normal breast bud emerging beneath the nipple on one or both sides. You do not want anyone to come near that area with a needle or knife as it may impair future breast development. You are welcome to start over with more detail.
