My 3yo DD1 has started being silly with how she talks- eg saying "What mummy doing?" instead of "what are you doing, Mummy?"
She has been speaking properly for months now- she gives me a little sly look when she does it too, to see how I react. Up to know I have just been replying correctly, like I used to do when she was first learning, but should I be doing something else?
She has a baby sister, but she can't talk yet, so no idea where this has come from. Unless she is trying to be babyish...
