Thanks Aimee, Laura and Julie for responding.                   I am going to make sure that Kev and Brad are on the right meds and doses for them.  Brad has not finished growing yet.  Even at 15 his last bone scan shows him to finish growing at 20.  He is a few years behind.  But like I have said, their levels are never in a proper range.  So, I will let you all know what the doctor tells me when the appt. date has arrived.    Thanks again!   Beth
