I am so glad your little boy is going well, it sounds like you had it all under control.   I just wanted to add that we have never modified our 7 year old SWCAH daughter’s diet to "fit in" with CAH.  That is, we don’t give her particular foods before bed, don’t give her extra sugar or extra salt in her diet.   Low blood sugar levels can bring on adrenal crisis but that doesn’t mean that we load our CAH kids up with sugar to prevent this happening.   The only thing I have done is give her Gatorade when it is hot and she has been doing excessive exercise, i.e. sports carnival, swimming.  For some reason swimming knocks her around a bit!
