Ask him to tell the doctor that he can share medical information with you and your siblings--of course, your dad may say "no," but it is worth asking. Try to find out when the doctor makes rounds and be there so that you can ask questions--no knowing is worst--the imagination can dream up all kids of things that are far worse than reality. Is there a ROnald McDonald house near the hospital, if so, you should be able to stay there at little to no cost so that you can spend time with your dad without having to drive so far to and from the hospital.
