My son was also 12 when he had fusion surgery. I thought I'd mention that I, too, have a very low bed. After my son's surgery, I thought that maybe his bed was a little too high up for him so I had him try sleeping in my bed. He was absolutely miserable trying to lower himself into my bed so I switched gears again and we put him back in his bed where he was fine, for the most part.
Something else I found helpful was keeping a baby monitor (I bought one just for the surgery and then gave it to a new mother I met) in his room for the first few days so I could hear him anytime I wasn't in there with him. My husband and I took turns sleeping in his room though, the first few nights, just in case he needed something.
While we were in the hospital, I kept a little notebook to write down all the doctors, nurses and therapists names as well as the meds my son was given and times they were given. I also used it after we got home in order to keep track of the times I gave him the meds. It really helped me to keep track of, and remember things and for quite a while, my son sort of liked reading it.
I know it's a really stressful time for you right now but soon it will all be over and it will be such a relief to have the surgery over with. Remember to get him walking as soon and as often as possible after the surgery. It really helps with recovery.
Hang in there!
