Oh it's like you have written about my DD1. As soon as she is in trouble she cries for Daddy. I think it's because she knows it gets to me and then she has the upper hand. So I have started just ignoring it and saying Daddy will be home later and carry on with discipline. If she is bored and I can't play with her then she will ask over and over again "is Daddy home now?" Drives me nuts and I think that is why she does it but I try to not let her see it gets to me.
