Preparing kids for my hospital stay

I'm going to be having surgery in a little over a week and it is going to entail at least one night in the hospital.  Both kids are concerned, with my daughter being more concerned, so I'm trying to prepare them as much as I can.  I'm going to list what I am doing but would love some suggestions to help them
1. Got books from the library to help them
2. Going to make something for easch of them to have while I am in the hospital...most likely a pillow or blanket.
3. Have them staying with friends during the day of a day after but going home with daddy at night.
4.  Keeping school schedule going as much as possible.
5. Talking freely with them when they ask question.

Any other suggestions?
