Charlie and Lola (2005)

A patient older brother talks his stubborn, imaginative little sister around, usually by meeting her logic on its own terms. Adapted from Lauren Child's picture books, including I Will Not Ever Never Eat a Tomato, it keeps their collage look, so it feels like watching a scrapbook come to life. Parents of a strong-willed preschooler will recognize every negotiation, and quietly pick up a few tactics. The sibling dynamic keeps it funny rather than cutesy, and older brothers and sisters tend to enjoy it as much as the little ones.
