As I'm sure you know, solids are just for experimentation at this age. She should still be getting the majority of her nutrition from breast milk or formula.
That said, there is NO NEED to worry about what she's eating. She'll be getting all the carbs, fats, and proteins from bm. Solids are just for fun. She could spend the next 6 months eating nothing but applesauce (solid wise!) and she'd be fine.
There's no need to rush. If she's not doing well with fruits right now, perhaps her digestive system just isn't ready to handle them it. Wait a month, maybe 2 and try re-introducing them to her diet. Most likely, once her GI system matures, she'll be able to tolerate more foods.
Good luck!
