My son went through a stage where he slept on the couch for awhile...it bothered my friends but not me. I figured that as long as he was asleep, why bother moving him...besides, moving him only woke him up and he'd move right back to the couch anyway...if I left him be, he'd sleep straight through the night. Same with my daughter, she actually preferred to sleep on the floor (and still does at age 14!). The way I figure it is, they were prepared for their first sleep over, and neither of them complain about sleeping arrangements when we go camping...so it was a nice trade off for me. I got to sleep through the night and so did they and we didn't have any hassle about it at all. As long as she is sleeping, let her sleep on the floor...there's no harm in it at all and is way less hassle to boot.
