My 4yo DD has a gift for making up words that are actually rude words. Do yours? How do you react?
Example, she has two toy white rats which she named Whitey and.... Shitey! "Whitey and Shitey rhyme together!" (quite right!)
She was just waving around her brother's lightsaber and shouting "I'll whack you with my whacker! I'll twat you with my twatter!"
