My daughter is 8, almost 9. And she told me a few nights ago that she had a lump on her chest on one side, so I had a look and it appears that she's starting to grow boobs, the other side has a lump now too. So I thought it wise to get a good, child friendly book on what's going to happen to her in the coming months/years. Any recommendations and advice on how to handle this will be gratefully received!
