Given being "special" in so many ways (hearing aids/adopted) she knows it! And uses it, truely sounds to me like more than anything else (hearing issues/developemental issues) she may just know how to get what she wants out of certain people. I have a 2yr 8 mo old, who is adopted (and very loved) but has some learning delays (was quite neglected the first few months and has a little DNA issue or two maybe) but is VERY intelligent and will "take a mile" if you let her. At home as well as here, there are "no exceptions" she is smart enough to understand right from wrong but has a bit of a "stubborn streak" she attempts to "push" as far as you will let her (just as any other two year old) the way I see it is, she is just the same as any other 2 yr old, delay or not (within reason of course, but I expect her to do just about anything I expect of a just 2 yr old, which is pretty much the same as a 2 yr 8 mo old) when she mis-minds she is disciplined when she doesnt listen she is corrected and if she throws a fit, it's not tolerated. Otherwise she will never learn.
