RAD behaviors to expect...?

The big question I'm seeming to have is pertaining to RAD. I've read about some pretty extreme situations on the boards and behaviors exhibited. I have been reading some books too, but am wondering what to expect since it seems to be terribly common in adopted kids. Do y'all have some examples of maybe moderate RAD behaviors/effects that you deal with that you could share? Just trying to get some of this figured out I guess and what I should expect, so I can have 'Aha' moments and not 'OMG' moments when I face some things. :Chewie: ----->Coffee anyone?
