Kevin McNamee has written a book specifically for kids dealing with sibling rivalry. It's interesting that the characters' names are the same as those in the dedication, so probably the author is writing from personal experience.
The Sister Exchange is a delightful picture book about Brianna, who wants to trade in her annoying little sister, Julianne, for a better one.
Julianne drives Brianna crazy by following her around and trying to do everything her big sister does. But when the older girl asks her mother if she can exchange her sister, Mom comes up with an amazingly creative way to solve the problem.
The delightful illustrations by Kit Grady do a perfect job of showing what the characters and settings look like.
I think every family with more than one young child would be wise to get this book and read it to their kids often.
