Ok well she is eating, but not normal at all!
It's probably normal. Both my kids go through spells where they don't eat as much as is "normal" for them. And then after a day or two, they gobble up everything in site. Not different from us, really. LOL! And it very well could be teething. I know that with Kate, we notice an appreciable decline in her eating right when she's peaking with a new tooth. Give it a day or too, try to get liquids in her for hydration and watch the diapers. My ped always says as long as they are making wet diapers 6-8 times per day, they are doing fine. If, after a few days, you don't see improvement, then it might be time to give the ped's office a call to talk to one of the nurses. But I'm sure it won't come to that!
Unless she has other symptoms like runny nose or fever or doesn't seem like herself, it is probably just a lull in the eating department. If that's the case, trust me, you will go through it many times to come. Emma was eating 4-6 oz every time, suddenly she was only eating about 2 and didn't want any solids, well, she was teething! Now she is back to eating again. Same with Sofia, she is getting her 3 year molars and hasn't been eating much lately either. Good thing about kids, unless they are sick, they will eat as much as is needed, and they will eat more or less during different periods. As long as she is getting at least a tbsp of fluids for every hour she should be fine.If you are really worried call your Ped. Like one of my friend's mom says, why worry alone when you don't have to.
