Commiseration
My 10yo dd does the same thing. I try very hard not to engage. I also remind her, often, that I am the mom and I can change decisions, make decisions, etc if I feel it is necessary. She doesn't have to like it. She does have to abide by it. (fwiw, I try not to change decisions often. She has a mind like a steel trap & if something is done one way once for one reason, it must always be done that way.
