Hi Angela, I'm curious what your endo is considering a high level of 17-hydroxyprogesterone. My son was expelled from three preschools between the ages of 2-4. During this time, the highest level he had was about 2,000. He has for the most part been controlled around 200. Like you, it seems it's more of a "control" issue. He gets very excited, whether through play or anger, and throws temper tantrums, and strikes out at whoever is within range. We tried everything, but what seemed to work best is the timeout in his room. I would suggest taking any breakables out of the room. We had to put a lock on the outside of the door because he wouldn't stay in either. He was told ahead of time that he was going to have a 5 minute timeout, but the time wouldn't start until the crying or screaming stopped. We used a kitchen timer and placed it outside his door and when he stopped throwing the temper tantrum, we would set the clock and when it rang he could come out. If he started the temper tantrum during the clock running, his time would start over. He knew and understood these rules. It was very difficult in the beginning because his tantrums could last for hours. After doing this on a consistent basis, he seemed to be able to get control quicker. These days, I don't need to use the lock, he will stay in his room on his own, he doesn't tear up his room any more because we made him clean it up and if he broke toys, they were not replaced. The consequences of his actions were clearly defined... It was extremely difficult in the beginning, and it takes a toll on your nerves. Increasing the dose of cortef is not the answer when their levels are good. The therapist is the one who suggested these behavior modification methods. Hang in there. It really does get better. Renee
