Well I'm happy to report that he is home now!
They had a nurse take the flight home with them and make sure he was settled in before she left to stay at the airport and fly home tomorrow.
He's doing well and will have a doctor appointment tomorrow morning to get everything straightened out.
Thank you again for all your prayers and words of encouragement. I'm sure it will be months before he is back to anything resembling normal, but he's on his way.
