In a large saucepan over medium heat, combine pudding, milk and sugar; bring to a boil. Cook, stirring, for 2 minutes. Cool 30 minutes, stirring often. Fold in cream. Pour into pop molds or 3-oz. paper cups; attach lids to molds, or if using cups, top with foil and insert pop sticks through foil. Freeze until firm, 3-4 hours.
