maybe she wants some "real food" like many of the things you are eating. many babies reject processed baby food (have you tasted it? ) so try preparing some of your own or start feeding her some safe foods from your plate. she doesn't need teeth for many of those things. don't give her too many different foods at one time remember that breast milk or formula is still very important and follow her pediatrician's recommendation on when to start safe solids but now may be the time. she watches what you eat so this may be her way of saying "how come if have to eat this stuff in a jar? " fyi: my daughter did the same thing!
when i try and feed my six month old daughter baby food she shakes her head like its sour every time.
