We visited our son today. He is in the high oxygen environment. It is hard to watch his chest almost collapse on each breath. He is starting to digest food and O2 saturation is good. It is hard to stand there and not be able to do anything but watch. He was alert and looking at me when I arrived and looked calm. He was more unsettled when they were feeding him but seemed to fall asleep eventually. It's only been 7 days. Patience, grasshopper.
