I am a parent but not with a child old enough to talk let alone watch a movie. But my wife and I went and seen the movie last night with another couple. There are a few scenes with Bella in some very conservative lingerie. There is one scene where she has nothing on and is making out with Edward in the ocean, all you see though is their bodies together. There are worse things on TV right now.
The birth is bloody, but again you see worse on CSI.
I think overall they did a great job with saying what the wanted without showing to much.
