Before I had my van to toss them into in an emergency I had a tarp in the laundry room that I could throw outside for them to stand on if we had to evacuate from the lower level and from the main level I would just toss all their stuff out the door cause it is right beside the door.

Than in the shed I had my wagon with many extra blankets to snuggle under and all of them would fit in there in an emergency it be squishy but it would work.

I also have an 'emergency evacuation bag' that was stored in the shed at the time had extra clothes and food and 'entertainment books / puppets' so forth cause my 'emergency location' had to be something I could access and well I do not have any neighbors I know well enough to ask for a key to their house so I chose the corner store and they were ok if we were to come and sit in the staff room quietly in an emergency so I needed something to 'keep them quiet' while waiting for parents to come pick up
