Terriblew Twos or Sick Sweetheart?

Savannah has been super gumpy the last couple days. I'm not sure what to make of it. She's been fussy all the time and throwing fits over every single little thing. She's been crying, whinning, and pounding her fists on the floor more than I've ever before. I would say she's not feeling well, but there are no signs of sickness that I can see.

So I'm stuck trying to figure out if I should discipline her or love on her more. Ah! Sometimes.....
