wow...I guess there are a lot of us that are experiencing this! We have not found anything that is really working well, so I look forward to the other posts.
We have done something similar to Rebecca when he whines. I tell him that I don't speak Whinese (pronounced like the word Chinese) that he needs to speak Big Boy. It usually works because he doesn't get his way and he is forced to talk right in order to get our attention.
