Either Charlotte is teething, or we are bad parents.
I think it's the teething thing. She just did not want to go to sleep or anything last night. She shrieked and shrieked. We fed her, changed her, offered her the bink, walked her, bounced her, everything. She would close her eyes for a moment, then scream some more. I was hesitant to give her Tylenol, because she wasn't running a fever and I'm not sure she's teething, and I don't want to drug her unnecessarily, but then she showed a lot of interest and quieted down when we gave her a chilled teether to "chew" on. That's what convinced me to at least try the Tylenol. It was very late, and I still had work to do, and Matt was at the end of his rope. She did finally settle down after that, so now I'm wondering if she was in pain that whole time, and that's why she was so upset.
This parenting thing is hard.
ETA: According to BabyCenter.com, here are some signs of teething.
What teething symptoms will my baby experience?
Experts disagree about whether teething actually causes symptoms — like fussiness, diarrhea, and fever — or whether these common symptoms are not related to teething at all and just coincidentally appear at the same time as emerging teeth. Regardless, many parents maintain that their teething babies do experience discomfort (though some babies get through the process with no problems at all). The symptoms most likely to trouble a teether include:
• Drooling (which can lead to a facial rash)
• Gum swelling and sensitivity
• Irritability or fussiness
• Biting behavior
• Refusing food
• Sleep problems
Also, it notes that teeth can start erupting (god, that just SOUNDS painful, doesn't it?) somewhere between 4 and 7 months.
