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.
 
Told through the eyes of a new older sister, this simple story lays out all the good things about being an older sibling, and just how exciting welcoming a new member to the family can be.
