Glad to hear things are going well. I wish I had seen this thread earlier.
Our two kids have had multiple surgeries over the years. It is not fun. It %^&*( sucks. But at least they CAN be treated. For which I am VERY thankful. Thankfully, our kids problems have been fixed as best they could be, and while cancer was a risk in one kid, over two surgeries, there was none. The waiting is the worst part.
Our kids have always been brave even during some very painful procedures which thankfully they do not remember. We remember and it scars me to this day.
The kids are tougher than the parents. Our kids really hated the IVs. The kids waking up is also been stressful. They would always move around and moan quite a bit so we would have to watch the IVs and O2 sensors.
It had been said but it should be said again. Hospitals, especially Children's hospitals, should be able to help you find near by lodging. One of our local hospitals has a hotel IN the hospital for patients families. I never knew this until we had a family member checked into a room for weeks. There is a Ronald McDonald House near the two Children's Hospitals in my area.
Both Children's Hospitals have very good play areas if the child is going to be in the hospital for a while. One play area is beyond awesome and is simply amazing.
For years I volunteered helping raising money for a local children's hospital. The staff would ask if we wanted to tour the facility. I NEVER wanted to go on the tour. I just did not want see the kids. It just hurts too much to see the really sick kids. Then my kids needed the hospital.

I got to know my way around that hospital.
We are so thankful for the hospital and staff. The staff in all of our visits has been wonderful. Bless them, for I could not do what they do every day.
Other people have been through this. Talk to the staff if things are really bothering you. They should be able to help.
Later,
Dan
