Ugh my daughter

Kacy

My daughter is almost 6 and is just about the worst behaved child when she's with us (or with her cousin). She doesn't listen to us at all she won't eat anything she just won't behave and whines all the time. And we can't stop it. We don't know what to do with her. Any body with some methods that have worked, I can google all day but I'm looking for something that some one has tried and seen a result from.
