My difficult child is very Jekyll and Hyde with her moods. She was upset and crying last night over consequences given for extremely rude behavior and name calling to 6 yr. old easy child. As soon as I walked past her, she starts screaming ""FYOU B****!!!"" and started throwing punches at me. After I was out of reach, she starts the crying again. We also have a lot of moments where she is very happy/giddy/hyper and then if someone speaks to her...usually husband or her sister, she'll stop whatever she's doing, glare at them and yell "WHAT?!?!" Usually she'll end up stomping off to her room or sometimes having to be escorted because the mood continues to escalate. Then, after a little while, I'll call her down and she acts like nothing happened. She remembers it when we ask but as she's over it, she expects us to be over it too. And we usually only get an apology if we ask. We've been trying to identify triggers for years and incorporate coping skills and behavior plans. But as there is no predictable pattern, we're stumped and we just try to keep ourselves and our expectations as consistent as possible.
