Food for thought...... Because our kids are supposed to be getting replacement doses ( and not higher than normal), some of the side effects of cortef are not really relevant to us. I asked a father a few years ago about the 'aggressiveness' as I was curious as to what to expect. This father (of a then 14 yr old boy) made a good point and I like it. He had never heard this was a tendancy and he was glad. He did not want to ever 'excuse' certain behaviors (like aggressiveness) because his son would have to learn to control something like that anyway. If we think it is normal, we might not try to curb it! Like I said, food for thought....
