All I can really do is make sure I stay up so he gets his meds, and keep him eating/drinking cold stuff so it heals up faster.
It's a little tough because my sleep schedule is all messed up. I'm waking up at 7AM and wanting to go to sleep by 10. WTF. Anyway.. I have to try to stay up until midnight, or he'll miss a pain med dose and be hurting when I need to sleep :(
I have all sorts of good stuff for him to eat, though. Even though he won't be able to have solid food for a little bit, I have lots of jello, yogurt, pudding, ice cream, applesauce, etc. And when he can have hot foods, I have a few flavors of mashed potatos :O
