Thanks for the input.  Alex is on the compounded hydrocortisone, which is why the doses seem so low to me.  He has no other symptoms of oversuppression other than the fact that he is so small.  Considering the fact that I am 5’8", his dad is 6’1" and his half brother is 6’4", it just seems strange that he is so little.  No one on either side of the family, male or female, is under 5’8" (I am the shorty in the family).  His weight is perfect for his height, but he is just tiny (27 inches and 20 lbs at 16 months).  It is just getting really frustrating.  Our next appointment with the endo is August 9th and that is when they are doing blood work again.  Thanks for all of your input.
