Dd (5) is sometimes a bit "creative" with the truth. This time it's serious. Her gold heart necklace, which I keep in a special jewelry box just for her in my drawer, has gone missing. I asked her about it & she denied touching it. I gave her the benefit of the doubt but now I've realised another bit of jewelry has gone missing. She denies any knowledge of it. But I don't trust her. Her behavior makes me feel quite strongly that she's lying and bluffing. I never would have thought that a five year old could be so cunning. I did manage to trap her into admitting that she did, at one time, put the necklace in one of her little handbags & I saw the look on her face when she realised I had trapped her. I'm sick about this & it's wrecking my relationship with her. I don't care so much about the jewelry; I do care dreadfully that she is such a clever liar. what to do? Please advise!
