I'm guessing that's a link to my post (won't open from the app), but having just been through it, I think the most helpful things were (bland) comfort food, bendy straws and a way for him to sleep upright comfortably. And of course, lots of patience and love.

We were fortunate enough to be able to have surgery close to home, so I am not sure about recovery on the road.
As max suggested, check out the surgery forum. I probably read a few years worth of posts in preparation.
Good luck and if something else comes to mind I'll be sure to update here.
