Not tired?

The other night, I was awake feeding Nicholas and I could hear Ryan crying and talking in his sleep. After I put Nicholas down, I went into Ryan's room to try to settle him down. He was still talking, so I rubbed his back for a little while. As I'm doing that, Ryan keeps saying over and over, "I'm not tired, I'm not tired, I'm not tired." He was FAST asleep the entire time!
