Can I Say it to the Dogs?

So Leora has been testing me lately on what words she is allowed to say. I admit that she hears us say things sometimes that aren't appropriate for her to say. A couple of days ago she told Emma to "Shut up". I told her not to say that to her sister. It isn't nice to say to people. Because I know she has heard me yell "Shut up" to the dogs I told her she could only say that to the dogs.

Yesterday morning she was playing with some dolls while I was getting ready for work. Her dolls were talking to each other and one of them said "What the hell!" I asked her what she just said and she ignored me like she does when she knows she did something wrong. I asked her why she said that and again she ignored me. So I told her that she shouldn't say that and it's not appropriate for little girls to talk that way even when they are playing. She replied by asking, "Well, Can I say it to the dogs?" I smiled at the question and said no not even to the dogs.

She may only be 3 years old, but is pretty quick sometimes.
