Hello. I'm the Mom of an 11 1/2 yr old daughter who is coming into puberty. In the last 6 months she's began to develop hips, and body odor and acne. She has not started her periods as yet...My question is about breast development...She is starting to get "buds" and, last week, she told me that one has a hard, sore lump underneath it. It under her nipple area and is about the size of a large flattened marble, and the surrounding area is not red or swollen. Is this a normal thing in development? (the other side is okay.) I don't recall experiencing this when I was her age...Anyone? ~MM
