DD1 about to start new school with older pupils so am sure will be period paraphenalia in toilets etc so seems right time to have that talk. Any recommendations for a helpful book to give to her-also have heard in past about giving her a pretty box with book/sanitary stuff etc. Don't really want to go into massive detail about sex just yet (or should I) so a book more focussed on body changes would be better at this stage.
