I'm a Big Sister

With an author's note about what big siblings need—extra guidance, reassurance, love—and sweet, engaging artwork, it's no wonder that nearly 4 million families have chosen I’m a Big Sister and its companion book, I’m a Big Brother, to prepare their young ones for their first big transition.

"Someone new is at our house," begins this loving, reassuring celebration of sisterhood from trusted author Joanna Cole.
