Hi!, No, I don't think that you were too harsh with your daughter today. You did the best that you could under a very difficult situation. Sometimes when a difficult child is in a rage they can get totally out of control, and there is nothing that will calm then dowm. You let your difficult child know that there are rules she has to follow in your house, and that is a really good message to send to your daughter. You should be proud for the way that you handles this difficult situation. Hugs to you,
