Drinking tea like a lady

I am trying to teach Gioia to lift her pinkie finger when she drinks tea.  This is a rather complicated exercise as her fingers seem to be attached together by some invisible webbing and when she lifts one they all move up and this just annoys her.  As a result of her irritation she no longers pours me a cup of play tea, she pours only for herself and then sips politely, holding her tea cup like one would a warm mug of coco in the middle of winter, a sure act of defiance.
