care and keeping of you too" an up to the minute guide on social dilemmas facing girls heading into adolescence. Juju chang sat down and talked about those challenges. ♪ Reporter: It's the secret life of tweens, no longer a child, not yet a teen, they crave independence but still need boundaries like in the movie "the sitter." What is your deal? Why are you wearing so much makeup ♪ on my way to the club going to dance all night ♪ I know I look good. Reporter: Now there's an updated handbook to let tweens read for themselves the candid answers to slightly embarrassing questions from body odor to peer pressure to social media. I sat down with seven girls, their moms and the author to discuss the often unseen pressures that tweens face. You teach them why something is or isn't safe so that they can then go out and implement these rules as choices. Reporter: Is there peer pressure to text because some are allowed to text and some respect. I say half of the kids are texting and instagram. I was at my birthday party and someone was using instagram. It was also kind of mean because it was almost like she was teasing that person. It scares me a lot from a safety standpoint. They don't have that many friends in their peer group so who's liking them? Reporter: The first question for cara, would you ever get your ears pierced without telling your mother? She'll say no. no. Because. Because it can bedangerous. No. No. No because I would need her permission. Reporter: You guys are definitely in the obeying situation. I'm going to check back in with you in five years and see. No, I'm kidding. Before then the book conserved a spark of ongoing mother/daughter conversations. I think it gives them talking points. There might not be a question to ask until they have information to ask about. I just said here, you can read this and she got a little embarrassed and said, mom, this is awkward but I did go into her room many times to see her reading it. Reporter: For "good morning america," I'm juju chang in los angeles.
