I went through basically the same thing with my 4 year old son. It was due to the liquid cortef and he was inches away from puberty. He was already showing major signs of it and still, to this day has residual behavior from this. I won't bore the other board members with yet another story about it, but if you would like to email me I can tell you what happened to us and what we did to stop it. Also, I can tell you what tests you should definately have done. Talk to you soon.
