As Laura alluded to earlier, last night was one of the worst nights I've ever had as a parent. Andy woke up after a little more than four hours of sleep, and then he basically refused to sleep for the rest of the night. Believe me, this is highly unusual for him. He hasn't refused to sleep like this since he was about 4 days old. He would scream whenever we lay him down in his crib, and he would jerk himself awake and scream whenever he dozed on my lap. My first thought was that he had a nightmare and was too afraid to go back to sleep. (Interestingly, one of our baby books lent a little credence to my theory — babies between 12 and 15 months are just beginning to actively dream). It was a good theory, but probably not correct. It turns out that he's cutting at least three teeth at once — an incisor that we already knew about, and at least two molars as well. We gave him some ibuprofen, on doctors orders, and he's been sleeping since lunch! Which is a darn good thing because he certainly needs it. I know I did!
