LOL-- I gave up even VETTING reading material at about that point, honestly... of course, you may not want to do that, as my then-12-yo found Mary McGarry Morris novels a bit... er... shocking, in spite of their (incredibly appealing) heft and number of bonus pages.
... you know you're parenting a gifted child when your 14yo combines Doctor Who with a traditional Japanese folk/ghost story, and decides that this is EASILY the best novel of all time, and is clearly a great NaNoWriMo novel. For this year, I mean.
Come to that, you might be parenting a giftie if your child was not yet into double-digit ages the first time s/he
completed a NaNoWriMo novel.
