Sleeping in a Tent

Well, we're off on another camping trip. This time, to spend the weekend with my family, who we don't get to see very often. We're hoping Peter will sleep soundly in the tent and not get too cold, or fall off his bed. He seems to nap OK during the day, but wakes up more often at night. We're taking lots of blankets and his special pillow and teddies.
Wish us nights of sweet slumber, please!!
