Bette, unfortunately we caregivers do just have fly blind. Take each day as it comes. He should be mobilised out of bed each day and start short walks. Getting into a shower is good for the soul and sitting out in a chair for a couple of hours is very good for the lungs and general recovery. The physiotherapist should also be stopping by to see Reggie.
This is just part of the general recovery process.
Kris communicated with a white board initially and then progressed to using the iPad with the speak It app.
I think that you just have to be patient with him. Encourage him constantly and of course love him to bits.
