Some people never learn how to talk to kids. They turn up the volume and enunciate with extra care, as if talking to a partially deaf immigrant. They sound as if they're reading lines somebody else wrote for them, or as if what they're saying is really for the benefit of other adults listening and not just for the child. Kids sense that and turn off.
