"Someone new is at our house," begins this loving, reassuring look at 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 reminds new brothers that they are just as special as ever.

With an author's note about what big siblings need—extra guidance, reassurance, love—and sweet, engaging artwork by Rosalinda Kightley, it's no wonder that over 1 million families have chosen I'm a Big Sister and I'm a Big Brother to prepare their young ones for their first big transition.
