Yes.

The thing that really gets me about this sort of scenario is that she may well have learned it from you. It's astonishing how quickly even small differences in reward can shape behavior, and it's very easy for the system being rewarded to be far more attuned to those differences than the system doing the rewarding.

This isn't even an exclusively human thing... I regularly have similar revelations about my dog, who is I'm sure much less charming than your daughter but nevertheless does OK.

Good on you for eventually recognizing the pattern and not further rewarding the behavior you don't want.
