First off, I wouldn't stress about solids too much just yet. I've heard of babies not "liking" solids at first -- especially ones who are exclusively breastfed. Go back to the beginning (cereal, then single-ingredient fruits or veggies) and try the food at the same time every day.
Also, symptoms of teething are identical to symptoms of ear infections -- eating less, fussy, sleepless, grabbing at ears. And, in our experience, ear infections interrupt sleep much worse than teething. You might want to call your pediatrician.
If she's not satisfied after nursing, you may need to add a feeding or supplement with formula. I'd check with your pediatrician or a lactation consultant to see how to handle that. With both teething and an ear infection, it can be uncomfortable to nurse or drink from a bottle, so she may not be getting a good full feeding, which is why she'd seem hungry too soon after nursing. Maybe going to more "demand" feeding until she's over this will fill her tummy and keep your milk supply where it's supposed to be.
