I need a nap

The last few nights Caleb has been waking up during the middle of the night to eat. Not such a big deal except he hasn't done this for the last month or so. I think part of his fussing his because of his teeth. At first I thought he was hungry, but he only nursed for about 5 minutes and then was out cold again. Last night he was super fussy and we put him to bed about 8 (normally, we put him to bed about 9 or 9:30). We were all exhausted so were in bed by 9. I was expecting that he would wake up at some point since the last time he ate was at 7:30. He woke up about 11:15 and ate and I thought we would be good for the rest of the night, but about 4:30 he was up again. He was fussing about his teeth - he has a very different cry when he is hungry, but when he is just upset about something he has pretty pathetic little whine and he "chews" on his lip. I fed him a bit more to try to see if that would help and he went right back to sleep. The problem was I couldn't! I was awake in bed for about an hour until Nathan's alarm went off. I think I finally fell asleep about 6:45ish and then was back up at 8:00. Can't wait for the Bug to go down for his morning nap, because I will be taking one too!
