Thanks for all of your advise back in the spring concerning my daughters’s extreme rage like meltdowns. I have concluded that it was indeed related to her high blood pressure at the time. After her adrenal crisis both her cortef and florinef were lowered and in less then a week she was back to herself. In fact she has now gone for two weeks in a row with green lights all week at school. O f course she is still an very independent three year old with an attitude but she is having typical tantrums for her age and gets over it quickly. When she was raging it went on for up to an hour of destruction and she could not be reasoned with at all and many times she just wore herself out. She came very close to getting kicked out of daycare . They are very attached to her and also felt that there was proably a root cause and they stuck with us until we found it. Thanks goodness.
