DD is in yr5 and her year are to start these sometime soon. She is quite a naive girl in a lot of ways, isn't very streetwise and certainly has no interest in boys (Thank God!). She has recently noticed that she is getting a bit of underarm hair, and is not so naive that she doesn't know where else it may appear, IYKWIM, but that is really where her knowledge ends. My dilemma is should I leave the whole thing to school, talk to her before the S.E lessons begin, or leave a suitable book on her pillow?!. Oh heck, my little girl is growing up! How have others dealt with this? Thanks.
