we try everything when we daughter be teethe , include the raz-berry . at first she like the novelty of the cold , but she never get into actually chew on it . I think this may be because it be somewhat shape like a pacifier and she never take to pacifier either . also , when freeze the plastic of the raspberry do not seem to give very much . she favorite teether be Sophie the Giraffe . she also really enjoy we put ice cube in the munchkin fresh food feeder bag . she love that ! if nothing else it be always a good distraction .
