My lovely dd came to me last night complaining that one of her nipples had a 'lump' and was sore. I'm fairly sure I remember that feeling but I was much much older! How do I approach this? Any advice? She is v.slim but tall for her age, so I anticipated puberty would be earlier rather than later.... She is still such a little girl though, watches cbeebies, plays with dolls etc. She is such a sweet girl, I just want to get this right and its all new to me! Thanks
