Our good day didn't last very long

My little Porter woke up. The doctors removed the ventilator and he kept mouthing "mom" but couldn't talk....he can't breath on his own. They had to sedate him and re-insert the ventilator. They said no attempt will be made for another 5 days. His pneumonia is worse and my poor sister witnessed the entire ordeal. They are so traumatized and I can't believe they could take anymore. I don't know what else to do or say.....
