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 Brother and its companion book, I’m a Big Sister, to prepare their young ones for their first big transition. "Someone new is at our house," begins this loving, reassuring celebration of brotherhood from trusted author Joanna Cole. Told through the eyes of a new older brother, 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.
