My kid is smart. She answers my questions smartly but sometimes she shouts at me when she doesn't want me talking or correcting her mistakes. All I do is hold her hand and talk in the nicest way I can and tell her she's acting bad. She just thumps her feet and makes faces. I ask her if she understood what I just said and she answers, "yes, mommy!" and that's it, no shouting. After some days will pass, there she goes again shouting at me when I tell her to do things. I'm really going crazy and I do not know how to discipline her.
