Our (almost) 3 year old has learned the art of sarcasm already and here is the proof.
Yesterday, my husband decided he'd had enough of CBeebies and switched over channels. Now, we all like CBeebies but there is only so much an adult can take in one day ;-)
Immediately our girl turned around and said "I don't want to watch your telly daddy, it is boring. I want my telly on."
Of course daddy said no. She continued to argue. Eventually he turned around and said "You must stop talking to me in that way, it is rude."
Without batting an eyelid she walked up to him and [insert high pitched, squeaky, sarcastic voice here] said "Shall I talk to you like this then daddy?"
1-0, slam dunk, game over!
