Who Said? Upsized Board Book by Silver Dolphin (Under 3)

The "Who Said?" series by Silver Dolphin Books is a beloved collection of interactive board books designed for babies and toddlers under 3 years old. This Costco-exclusive upsized edition features the same adorable lift-the-flap and touch-and-feel elements found in the standard editions, presented in a larger, more durable format perfect for little hands.

Each book in the series invites young children to discover which animal is making a sound, with peek-through flaps on every spread revealing a colorful surprise. Tactile elements including fuzzy, fluffy, and silky textures provide sensory engagement, while a surprise mirror element delights babies with a peek at themselves. The charming illustrations are created by award-winning illustrator Yi-Hsuan Wu.

Silver Dolphin Books is an imprint of Simon & Schuster specializing in interactive children's books. The "Who Said?" series titles include Who Said Moo?, Who Said Boo?, Who Said Peep?, and Who Said Hoot?, among others.
