Apparently he sleep walks!!

Oh my! This is scary. His daycare teacher came to my classroom this afternoon to inform me that Joshua was sleep walking at nap time today. He got up off of his cot and walked around the room. He never opened his eyes and she put him back on his cot. He never woke up. I guess I will have to put the gate back up. I'm scared he will fall down the stairs now. He has been coming in our room almost every night and I thought he was awake, maybe he isn't.
