I do think it is a test. She was used to getting away with more at my sisters. I think she is testing the limits here. Also, she is not used to the word no so that just sets her off. She was told she could not open a present early, and that was what made her be so out of control last night. I am hoping after she sees we mean what we say here she will act accordingly.But I do think a system to where she can see exactly what is expected of her, and what happens when she is good/bad would help her to understand the rules better.
