Some rough times since the last time I visited. I am sure you have heard of tough love and consequences of decisions. Maybe treat your daughter in the same context. It appears that you canceled plans to going skiing because your daughter had a little fit. Why did you do that? I would think the sting of seeing her brother having a fun weekend of skiing with you might have had a better affect than standing your ground.
ON a parenting board I had a mom tell me "reward good behavior and ignore bad behavior unless it is life threatening". When children see that good behavior is rewarded....they too want that reward. So will change their behavior accordingly.
Think about that one....you gave your daughter all the power when you thought that by making demands you had the power. Sometimes when walking quietly the biggest stick isn't always used as punishment.
