The referral is complete and will be seeing an Endocrinologist in two weeks. As Zachary's pediatrian says, "one of these days one of these doctor's will know what this is." He said to expect talk of another brain MRI and other tests. So, it's a new Endocrinologist for November and back to his Neurologist in December.
Pray that Zachary gains weight and that we can figure this out. He has been the exact same weight for 3 1/2 months now, and his developmental delays are getting much more obvious now that he's getting older. (18 months old and not sitting up, for example) God knows, and I'm praying one of these doctors will say "I know what that is!"
