Sick Baby?

I don't know if Zeraea is getting sick or not, I feel dumb. I should know something like that, right? Last night she was up about every 10 minutes just whining, almost like she didn't feel good. I took her temperature and it was 99.6, a little high for her. I checked again later on and it was 99.2, then this morning it was back to her normal 98.3. So I'm not worried about a fever, but I just FEEL like there is something wrong with her, she wants constant cuddles (which I don't mind), but she is so darn grumpy! She cries at anything and everything, it's so sad to watch. I feel so helpless and am not sure what to do. I am thinking it is her teeth since they have been bothering her for a couple of weeks, but never this bad. Kevin thinks she isn't feeling good either, just from her mood. Times like this makes me feel like a bad mom. I want to be able to help her or to know that she needs help. She is finally taking a nap, and hopefully she will take a good one cause she needs it, and maybe in return it will make her mood a bit better!
