From the author and illustrator of the bestselling In My Heart! This oversized interactive book is a heartfelt look at the wonder and excitement of waiting . . . and waiting . . . and waiting for a new sibling to arrive. The charming protagonist is so eager to step into her role as a big sister that she's starting early! She sticks close to her mama so she can sing songs to her sibling-to-be (loudly, of course) and explain all the great things waiting in the outside world (cupcakes! strawberries! swimming!). Quaint line drawings and lovely patterns lend a breezy, lighthearted atmosphere to the story, and a variety of playful flaps add gentle humor, showing the new baby blissfully tucked away in its mama's belly. A joyful and celebratory ode to the growing family for any sister- or brother-to-be. The Growing Hearts series celebrates the milestones of a toddler's emotional development, from conquering fears and expressing feelings to welcoming a new sibling.
