I may have mentioned this to you before, but I had an older brother who was hit by a car when I was 8. He was in a coma for 27 months (never woke up) and died 1/1/73. He was in various hospitals, and even at home for a stretch, but basically, nothing could be done, as brain trauma was extensive. Let's just say I couldn't stand the sound of a siren for several years without freaking out.
But...we were blessed. First, my parents never had to travel beyond where we lived (Chicago area). They never had to make overnight stays in faraway places. And as for meals, our neighborhood "rallied" so many times, with meals, gifts of all kinds of foods, moral support, watching my little brother and I, etc. etc. And my Mom truly felt that she had 27 months to "prepare" for his death. She told me two things that have really stuck with me.
First, what my parents went through was awful, but they DID have time to prepare. Think about how many people have kids taken from them in a split-second. That is a near-impossible tragedy to reconcile in your heart and mind without serious time, talk/counseling, etc. Second, when the idea of an RMH-type house was first brought to our area Kiwanis clubs (it was not RMH at that point), I happened to be club president. When I told my parents about it, my mom avidly urged me to push for our club to participate, fund, etc., in any way we could. She noted how they came across so many people at various hospitals and rehab centers who were from out of town and out of state, and how, back then, it was so difficult for them coping with the dual problem of an injured/sick/surgical child AND dealing with the "healthy" kids, PLUS the day-to-day of things like food, lodging and, oh yeah, school, clothes and the like for the "healthy" kids.
Yes, it's TERRIBLE for the afflicted kids and their parents. It's terrible for the "healthy" siblings, too. But...there are a lot of "bright" spots, too, RMH (and similar programs) being one of them.
