Patricelli continues her series about a captivating bald baby with two more board-book volumes. Tubby deals with the nightly ritual of a bath that begins with naked time and a chasing game and ends with a clean, dry baby in a fresh diaper. Potty focuses on a toddler milestone: the first time using a potty. After watching what the cat does and the dog does, Baby realizes that humans have traditions of their own. Few book creators today are producing original board books as witty and engaging at Patricelli, and her latest offerings more than live up to her previous ones. (Ages 1–2)

A new toddler title charts a crucial achievement.

There comes a point in a toddler’s life when going in one’s diaper is only one possible option, and the question must be raised: Should I go in my potty? With pitch-perfect humor and pacing, Leslie Patricelli follows the inner dialogue (sure to have little ones shouting responses) and hilarious actions of everyone’s favorite Baby, winding up with an over-the-top look of surprise and delight that will have both parents and offspring laughing out loud. "I did it!"
