Looking for ways to encourage my son to sleep in his bed.

[Tigger9406]

My son just turned 3 in Aug.  For the past maybe 6 months or so, he's taken to sleeping on the floor; this includes naps.  At bedtime he would start out in bed then move to the floor.  For a while, I would put him back in bed when I went to bed...but he would always be on the floor when I got up.

We just recently moved from MI to PA...he slept in his bed the first 2 nites and now sleeps on the floor.  Whenever I ask him why he sleeps on the floor, he tells me cuz I can or cuz I want to. 

I was wondering if anyone had any ideas on how to encourage him to sleep in his bed.
