I'm the same at AmandaKDT. I also keep warm blankets in my van, because I'm able to open the doors for inside the house. So any kids that are old enough to run outside on their own can safely wait in the van while I'm getting the younger ones out. A copy of all of my child information sheets is located in my first aid backpack, and we evacuate to a house two doors away.
All of this is written out and posted at my front door and I email a copy to parents when I send them the child information sheets to fill out. I also keep my evacuation/floor plan taped to the board that the attendance records are on, so I can grab that on my way out the door.
