Hi where will he be having it? Will he be sedated? I used to think all children were, but have heard of some children that weren't, which unless they gave me a very good reason, I would not allow my child to go thru one awake, since they can let them sleep thru it. . Justin has had many caths, the hardest part for him has always been laying still for the couple hours after them, the caths themselves he doesn't remember at all. I guess if I had some advice I would find out if they have dvds in the room he'll recover in and if not take something to watch movies one. Most likely he will be home the same day
