I’m not sure which Alice book you are referring to, but you mention the early Alice books, so I’m guessing it was “Lovingly Alice,” in which Alice is in 5th grade, and she and her girlfriends are discussing menstruation and sex at a sleepover. The suggested age group for this book is 9-12. I’m sorry if you feel that your ten year-old daughter should not be reading about such things, but I’m afraid I disagree with you. Girls are menstruating at an earlier age and we also read about girls who are still children themselves becoming pregnant. I and my publisher believe that girls should have information about sex and pregnancy, not be kept ignorant of them. If you don’t want your daughter to read books that your library has approved, then you should read the books ahead of time. But I do think you might form a good relationship with your daughter by reading these books together and discussing the things that she doesn’t understand.
