Somehow saying I can tell you now must have unjinxed me, because people, he is IN MY LIVING ROOM RIGHT NOW!! And what is he doing? Living!! The endocrine nurse we talked to said she hasn't seen his MRI but thinks the doc at the hospital may have worded it wrong. He might still have some small part of his pituitary, but he might not. Either way for now they are treating it as hypopituitarism and they have every confidence that he will be a relatively healthy happy baby/child. Your prayers must have worked. Thank you so much for being so concerned. He will need to monitored very closely and have numerous medicines and shots, but as far as they can tell he is going to live and he will be fine.
