Crabby, crabby

He's taken to being crabby at night. I'm not sure if it's because he's teething (I sure hope so because that means it'll go away) or if he's just so tired. Last night when he came home he was really tired and fell asleep for daddy for about an hour. He woke up, we fed him, he played for about an hour, at again and went to bed. Of course he woke up at 5am this morning all happy as could be playing in the living room with daddy while mommy finished getting ready for work. Oh well. Hopefully it's just the teething because that will go away once he finishes getting his teeth in. Cross your fingers.
