R.Y.
I don't know this hospital at all. My children were both in the NICU as newborns but not in the hospital since then. I found talking the the hospital social worker and case manager was helpful and they had more time to answer the background information type questions. The social worker for my son did some research online and gave up a bunch of printed information.
My grandmother has been in the hospital a couple of times in the last few years. Someone really did need to be at the hospital with her most of the time (not 24 hours but at least several hours every day). My mother and her 3 siblings took turns. The nurses made some mistakes with medication and nearly caused a fatal relapse. I know this is not what you want to hear. If you have to go back to work see if there is another relative of friend that can be backup for your wife so she can get a break.
I hope your son continues to improve.
