I only have sons, but it is a fact that girls are developing earlier than they used to. This was true for my nieces. There are many theories as to why this is happening, but the fact remains that it is. Don't be alarmed. With my boys, it was a real shock when they started to become "men". Logically moms know it will happen, but when it actually DOES begin to happen, it is a jolt. This is also the time when eating disorders can develop, so tread carefully regarding her changes. Makes me glad I only had boys. :0)
