I assume you mean she wont put food in her mouth herself?? My little boy was really not interested in food (he's 9.5 months) until recently (either off a spoon or finger food). Things like breadsticks are fab as you i'd put one end in my mouth and encourage him pulling it/biting it. Or he will feed me while i feed him finger food and then he'd start doing it himself.
sometimes really big bits are good (whole banana) or letting them choose from your plate...big bits of pasta etc? maybe she has had no teething pain and therefore has had no interest in putting anything in her mouth herself yet. good luck!
