Louanne Pig in The Perfect Family (Revised Edition) (Nancy Carlson Picture Books)

Louanne’s an only child. She thinks that it would be fun to have a big family, just like her neighbor George. He has five sisters and four brothers—the perfect size. When her parents have to leave town for the weekend, Louanne jumps at the chance to stay with George. But during her stay, there’s too much snoring, a long line for the bathroom, and absolutely nowhere to be alone. Maybe three is the perfect number after all!
