Our two and a half year old daughter is argumentative. There will be times when we’ve told her to do something in a clear manner and she will outright say “No, I will not do...” (fill in the blank.) I realize that I’ve contributed to this problem by trying to explain myself with her in the past. But how do I break her out of arguing? If she tells me “no” what kind of discipline do I follow through with? Also she will sometimes tantrum but then refuse to sit in her appointed “tantrum chair.” Please help!
