Rereading Twilight through an adult's perspective is always an interesting experience. Obviously, Edward and Bella have to have the narrative autonomy of adults to a certain extent. For example, Bella being "born middle-aged" and having pretty laid-back parents (compared to some) allows her to move through the plot more easily. Sure she gets grounded every now and then, but she can pretty much come and go as needed. Naturally, Edward and his siblings aren't going to be treated as "children" what with most of them being 80-100 years old.
That being said, there are times throughout the story when I wish Carlisle and Esme were a little more "parental" towards Edward and Bella specifically. It wouldn't even have to be proper parenting- if they showed a little more active concern and offered guidance, that would be enough.
When Bella shows up with a broken wrist and a story about her "best friend" kissing her against her will, it would have been nice if Esme had talked with her. Even "I know you're having relationship problems, and I'm here if you want to talk" would have been good. I think it would have been especially interesting if Carlisle and Esme had looked at Charlie and realized that he couldn't fully guide Bella because he didn't have the full picture of everything she was dealing with, so they stepped in to support her more.
I know having active parents kind of kills the teen drama of it all. These books would never work if Edward and Bella were wise and mature all the time. But there are still times when I wish the parents had seen these teens floundering and stepped in a bit more.
