Is that a good idea?

Today at nap time we went about our usual routine of a story and song. Scott then said he wanted to read some stories to himself, proceeded to make a stack of about 8 books, and said "Is that a good idea?" I helped him get under his covers and settled with his books and then I left the room. About 30 minutes later, while I was on the telephone, he began hollering that he had to go to the bathroom. After taking care of that and getting him back in bed he yelled out that he didn't think he could sleep today. I suggested to him that he sing a song, read a story, or snuggle with his animals. He said that wouldn't work. I told him to think of idea and when I was finished on the phone I would come help him. When I went in to him, he was wide awake and I asked what he thought of to help him fall asleep. He said, "I think I should play with toys. That would help me sleep. Is that a good idea?" :)
