My lo is becoming a very naughty girl, even talking back! She learned to hit from the baby-sitters daughter, she now smacks you in the face for no reason. She gave my 10 year old son a black eye with her toy (she felt bad, cried and patted him). She throws all her food on the floor when she's done. We've tried firmly telling her no, which she now says back to you while shaking her head. Tried slapping her hand, that doesn't work. I've tried taking her plate away before she can throw her food down, but she begs for food off your plate or insists to have her spoon or fork.

Don't get me wrong, she's not always naughty, she does the sweetest things too
