My DD is 9 and one of the smallest in her year at school. I haven't yet had "the talk" with her and I'm not yet aware if any of her peers have started their periods yet, though I have a niece 6 weeks older than DD who has developed rather rapidly (though don't think she's started her period yet either). I don't remember finding out about it all myself till I was at least 11, and I didn't start periods till I was 12-13, but I know lots of girls nowadays start much earlier than that. Is it time to do it now? Any tips on how to do it/what to say?
