My 4 year old did this as a baby. He had no interest at all. I backed off and tried again a month or so later. He would eat some baby food, but still liked his bottle.
When he was about 9 months old he wouldn't even let me get a spoon near him. I started giving him finger food - whole wheat bagel pieces, cooked pees or carrots, banana slices, pasta - anything that would be safe for him to eat. He loved it! Turns out his is very much an "I do it myself" kid. I know all kids go through the "I do it myself" stage. He's still there 3 1/2 years later.
Try not to worry. Maybe back off for now and try again in a couple of weeks. She's getting everything she needs, nutrition wise, from the breast milk. But her body is probably ready to start practicing solid foods. I bet she'll be interested soon.
