D.D.
Have you tasted the baby food in the stores? It's awful. I would mash up home cooked carrots, potatoes, squash, and any other veggie instead, with butter added, or ground up meats. My Kitchenaid Mixer has an attachment for grinding up any food that I want for baby.
Add a little salt, and I bet she will eat it. A lot of kids this age seem to stop eating, as well.
The fact that you are still breastfeeding is wonderful. I would keep her tasting new things, and not be too concerned about how much she eats. The Seattle times had an article about how breast feeding helps the baby up to 2 years of age!
