Oh, Brother... Oh, Sister!: A Sister's Guide to Getting Along (American Girl Library Series)

An especially great parent buy, this book is full of ideas and talking points for handling the ups and downs of sister-and-brotherhood. Inside there are tips on teasing, tattling, fighting, as well as playing and staying close as a family. "Super sister extras" in this book include photo frames, door hangers, and a "Sibling Constitution" that encourages siblings to agree on their rights and responsibilities as they strive to "create a more perfect relationship and a happier home." And what parent could resist that?
