Over the XMas holidays, DD slept thru the night, no waking at all for 2 nights. Then she woke once or twice for paci, no problem, could do it with my eyes closed. Then, last Wednesday, she woke up many times in the late evening, and by 1:30am was wide awake. I finally fed her, which I normally don't do. She ate the whole bottle and slept from 2am - 5am. Then it was up and down until she got up at 7:30am. Naps all day were progressively worse and she was unusually cranky, and Thursday night I figured she'd be exhausted enough to really crash out at night. No luck. At 3:30am she was wide awake. I let her talk for a long while until she began to cry. Then I went in, gave her the paci and tried to leave. Immediate crying. I tried repositioning her in the crib, patting her, anything. Nothing worked. Finally she fell back to sleep around 5:30am and slept till nearly 8am. We were going out of town about 3 hours on Friday, and I figured she'd take a nice nap since we left around her afternoon nap time. 1/2 hour!! Then she refused to sleep again until bedtime which was an hour an a half earlier than usual, and no bath. Just bed. She fell asleep well, then woke a couple hours later at which time I decided maybe it was her ears or teething (she has no signs of teeth yet though) and gave her some tylenol. This helped I think, and she slept until 2am when she again woke wide up. It was the same as before, and I finally got her back to sleep around 3:00am, no feeding, just doing anything else. She slept till 6am or so before waking for the paci, and up for the day at 8:15am. We decided to be on the safe side and took her to an urgent care to make sure her ears were ok, and they were fine. So what the heck is wrong? Why all of a sudden did I get two perfect nights, and then this hell again? I'm sure she's overtired, but I can't get her caught up because she isn't napping well. This feels like such a vicious cycle that I can't get out of. And if it's teething, my god how bad is it gonna get when I can actually feel buds? Please tell me I am not alone in being enormously sleep deprived even though my DD should be well over this stage by now.
