This sturdy carry-along boxed set collects four previously published Sesame Street photographic board books that touch on significant milestones as babies become toddlers and toddlers get older. Too Big for Bottles follows Baby Cookie Monster as he masters the art of drinking from a sippy cup. In Too Big for Diapers, Baby Ernie learns to use his new potty. Big Enough for a Bed is about Elmo’s move from a crib to a toddler bed. Big Enough for a Bike is the story of how Zoe learns to ride her brand-new tricycle. Crisp, bright photos and brief, matter-of-fact text will reassure toddlers as they, too, attempt to master important growing-up skills. This is an indispensable little library for all families. The box has a plastic handle and Velcro closure. | My Growing-up Library (sesame Street) by Kara Mcmahon, Board Book | Indigo Chapters
