My 2 1/2 year old does the same thing! When I am telling her something she doesn't want to hear, she points at me and says "No, you stop!". Aggravating isn't it? This behavior has also come with bossing my husband and I around. I just sternly remind her that it is not ok to talk to mommy that way and as long as she is telling me what to do instead of asking nicely she won't be getting anything from me. She seems to be catching on. Sometimes it goes so far that she as to stand in the corner - she hates that! As far as the fits of frustration when she can't communicate something, I can't help you there. My little one is perfectly content repeating the same unintelligible words over and over and over until I decipher them. I'm not sure what would be worse the fit or the repeating of the same garbled words over and over.
