Visiting your grandparents is always a treat, but it can also bring out totally different sides of your personality. Meet a little girl who bounces between two extremely different moods while spending the day with her loving Poppy and Nanna. When she is feeling bright, cheerful, and ready to play, everyone calls her Sweetie Pie. She brings smiles and sunshine into every room she enters. But watch out, because when she gets tired, cranky, or frustrated, her grumpy alter ego takes over. Suddenly, Sourpuss arrives with frowns, scowls, and a whole lot of attitude. Her grandparents know exactly how to handle both versions of their beloved granddaughter with endless patience and love. This delightful, funny story perfectly captures the big emotional swings of childhood. It will make you laugh as you recognize your own sour and sweet moments throughout the day.
