"Someone new is at our house," begins this loving, reassuring celebration of sisterhood from trusted author Joanna Cole. 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. 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 nearly 4 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.
