Kitty's favourite word is No! She doesn't want to clean her teeth, eat her vegetables or, worst of all, play with boring cousin Melisso. In fact, Kitty can't seem to stop saying 'no' but when Dad tells her he doesn't ever want to hear her say 'yes', she discovers that that's exactly what she does want to say! When she breaks one of her favourite toys, she finds she does want to tidy her room. When Dad says he doesn't want a goodnight kiss, Kitty decides she'd like to give one. When she's bored because Mum and Dad are having a lie-in she does want to play with her big brother, Daniel.
