It's funny because this morning actually she brought down her baby doll and said to me..."Mom, I'm the boss of my baby." LOL and I said, "Yes honey you are...does she listen to you?" And she said..."yes, she has to."
Your daughter sounds so much like mine. DD 3.9 does this with her 'babies' be it a doll or her prized stuffed animals.
And I handle the interrogation the same way. Did you not hear my response? Even ask her to repeat it and that is when she finally accepts the answer. (Most of the time and I think more so because she knows I'm not budging.) We also do timeouts and taking away privileges but are finding we use timeouts less and less. Does the intensity of the interrogation go up as they get older? If it does ... I really have my hands full.
