teething or ear infection??

So the past 2 days Audrey has been crankier than usual, not eating much, and has not been sleeping. She is usually a pretty good sleeper and a great eater. She barely drinks any of her bottles. Today I've had to let her cry some before bed and naps because she just won't lay down and sleep even though she's tired. I think I see a top tooth poking through but I'm worried it may be an ear infection. She just got over an ear infection and she didn't act anything like this. What do you ladies think?
