I have no idea where it's coming from. She doesn't use 'like' yet, to be fair, but she does use the Australian Questioning Intonation where the end of the sentence goes up? Like it's a question? Even when it's just a statement? Arrgh. She alternates this with dropping her aitches and using remarkable glottal stops. I don't think I talk like that.
She is nearly four. Anyone give me any hope for it being a short-lived phase?
