Children generally fall asleep quickly and sleep soundly at night, regardless of where they sleep. In the absence of any problems, most are asleep 98 percent to 99 percent of the time from lights out to final waking—that is, they are awake only a tiny fraction of that time, perhaps five to ten minutes during the night in all. Even during those five or ten minutes, they are drowsy, usually barely aware of anything other than the need to find a comfortable position and return to sleep. Thus, for most of the night children are not conscious of where they are or of who else is or is not with them.
