Sometimes babies/kids go on "food strikes." Maybe ask your Pediatrician about this....
main thing is she is still taking her bottle... make sure she gets adequate intake this way at least.
Do you give her her solids before of after the bottle? Maybe is she just full?
Is she sick or not feeling well in any way? Sometimes this affects their eating. Or, have you looked in her mouth? If a baby has "Thrush" it will look like white patches in the mouth.. and this causes discomfort when eating/nursing.
Teething also affects their eating/nursing.
If there are no other "symptoms" maybe just take her to the Doctor..... even to just rule out anything else.
Or what are you feeding her? Sometimes, some foods may irritate the mouth or cause gas...or maybe she needs a different texture... is she on stage "1" foods or stage "2"? maybe try something different...?
How puzzling. My children, they would get less interested in eating when they were either teething or sick. But then these are more obvious "symptoms." But all babies are different.
I would just ask the Pediatrician.... to rule out anything.
take care,
