Our 9 and a half year old has been asking a few questions of late about human reproduction. He doesn't know about 'sex' yet, as such, but he is getting interested in the biological mechanics of it all. I noticed you can still buy the book "Where did I come from?" which my parents gave to me over 30 years ago. Is that still the 'recommended text' for pre-teens, and if not is there another book you would recommend?
We will have a chat with him as well, but he's quite bookish and academic, and I know it'll sink in further if we give him a book about it as well.
He has a younger brother, who's 7 and a half. Would you tell them both? Or wait? Just looking for opinions.
