Sleeping on the floor?

This morning at 5:00am we heard one of Seth's toys make some noise (a monkey laughing). I thought, maybe he got out of bed or maybe he threw a pillow at the toy. There were no more noises so we fell back asleep. At 6:00am we heard the same monkey sound and then the sound of a seal. We were really confused at this point. There were no more noises so Jerald went back to bed - but I couldn't sleep. We both got ready for our day - and finally at 7:30am we went to wake him up. He was sleeping on the floor with cuddly and his pillow. He couldn't really explain to us why he was on the floor - but he was in a great mood and seemed well rested. Is it possible that he slept on the floor for 2 and 1/2 hours??? At least the rug is comfortable...
