We have been going through this off and on each time our 8 month old gets a new tooth (or set of teeth, they seem to come in two's for her). She now has 6 teeth, two on bottom, four on top. Anyway, I thought she must be the pickiest eater in the world, because my two older ones ate ANTYHING we gave them at that age, and enthusiastically. Feeding this one was like a battle just to get a few spoonfuls in sometimes. But we did discover that as long as we just tried at each mealtime and got a few bites in, we should consider that a successful mission :) And let her have the bottle as much as she needed, which she seemed to crave while teething. (Normally I would be nursing, but this time around I had to have a surgery that required medication unfit for nursing, so this one has been bottlefed since 3 months sadly.)
Be encouraged that your daughter is still getting most everything she needs from breastmilk, and if you can just keep trying solid foods, eventually she'll enjoy it. I really think it's the teething pain, ours just doesn't eat much when she is cutting teeth.
I did discover some baby food our daughter really likes. I bought it at Henry's market. It's called Healthy Time, and it's organic. They have great combinations of stuff, and you can get combos that don't have the allergens you are supposed to watch out for at this age (like egg, wheat, etc.) that a lot of the 3rd stage mainstream brands like Gerber will include.
It's cheaper than Earth's Best, and way more options. Our daughter had Jasmine's Chicken Luau yesterday (peaches, apples, chicken, brown rice) and LOVED IT! Today she will be doing Veggie Stew (lentils, carrots, brown rice). Hope that helps :)
