K.U.
My DD is 4 can get this way, but usually it's when she is overtired. Personally, I would just ignore them - let her run to her room, and don't give her any attention for her outbursts. She'll have to learn to get over herself and not act like such the drama queen. It's okay to tell her you are not mad at her and you don't mean to hurt her feelings, but really, that's where it needs to end. My daughter's approach is to walk away and sit pouting with her head hanging down. I will tell her I am sorry for hurting her feelings, but I also sometimes have to talk to that way if she doesn't listen the first time I use a "nice voice"
