Kate is a Daddy's girl. While she has always treated Jenn and I differently during diaper changing, fit-throwing, etc. the favoritism has always been somewhat mild. Potty training, apparently, is another thing.
Kate is still making great progress on the potty - ever since she got her own little pot like Simon and Jakey's, she's happily toddled to the bathroom, de-pantsed and gone by herself, needing assistance only for re-clothing (not a toddler priority) and occasionally with hand washing (although she's pretty good at that in her bathroom).
When Jenn's around, that's the only potty she'll use. Insisting to go to the second floor to use her Potty. For Daddy, however, she's actually requested several times to use one of the adult potties with her seat on top - the very thing she was rebelling against two weeks ago. Guess she wanted to be independent in more way than one.
