The past few days, I have woken up to see my son sleeping on the floor. He is in a toddler bed and did not fall out of his bed, but got out and decided to sleep on the floor instead. He's also been waking up about an hour to hour and a half earlier than usual with no change in naps or bedtime.

If I see him get out in the middle of the night, I will go put him back in his bed once he falls asleep and he doesn't go back to the floor. If I don't see before 4am, I leave him on the floor as he seems fine and comfortable there.

Is this the sleep regression???
