My son did the same thing, since it sounds like your baby is about 7 months old, I wouldn't worry to much. A lot of babies are only on breast milk at that age anyway, you really do provide everything she needs. At that age in lie it's more for a sdaily routine then actually nutritional value that they eat solids, (excluding cereal). If you like to nurse I wouldn't really push the issue and let her, it could just be a growth spurt or a confort thing. I would stuill offer foods but don't fight about it, it's not worth the worry or having your day ruined.

P.S. With my daughter as she got older and needed the foods I would just put thme in her bottle and she would eat them like a veggie shake with breast milk..... It's sounds bad I know but we do what we have too right, and she loved it. She too was breast fed but took bottles when I was at work.
