hi I know what a rough time this is, I would just follow Adam's lead tell him he can ask you any questions and you will be honest, Justin never liked talking about surgeries much so I would wait for him, but let him know to let me know if he has questions or fears.
first i would make sure you have a small 9like a throw size pillow to "hug' after surgery,it really helps w/ the pain Justin also used an uglydoll.com as a pillow for his last surgery and it worked so great we actually bought a couple for friends having surgery.
a stuffed animal from home should be fine especially if it comforts him.
also his gameboy, the hospitals usually have some game systems, but we alwasy take justin just incase there aren't enough, some of the hospitals have systems in each room, so i would call and ask what they have, and what kind of system so you can take a new game for him, also ask ifthe have vcr's or dvd players and take some movies, (alot of the ones they have a kid hospitals are really young, so be safe and take some he likes.
I don't know what Adam's intests are but Justin always liked legos when he was that age and they are easy to do sitting in bed, also take deck of cards. I don't know if you have a laptop if not ask the hospital if they have any if Adam likes talking online to his friends, if not maybe you could borrow one
where is he having surgery?
yes take Button up tops, it is pretty painful at the beginning to lift your arms over your head to put tshirts. Justin usually just wore shorts when laying around his room and would throw a hospital gown on to walk around, if he didn't have a robe. just have a button shirt to come home in at least.
here's the link to Justin's page, if Adam or you have any questions we will answer them as best as we can
oh a biggie if you have or can borrow a recliner it really helps at home both for sleeping and hangin around the house the first couple days,
