For you and Toni, Julia S. is the expert.  Why don’t you go through the archives?  If everything is OK for now, maybe don’t bother with it.  For Toni - you and your husband are almost exactly average height so your son doesn’t have the genes to be short.  Circadian dosing has worked for other kids who are gaining weight and not growing well.  You don’t dose them before bed and give them a dose at about 3 AM.  The bedtime dose can suppress growth.  The theory is that naturally your body needs cortef starting at about 3 AM and peaking when you wake up.  You naturally produce very little in the late afternoon through about 3 AM.  But Julia is the expert!
