Caution: Babies at Work! These babies are busy building a wonderful playhouse in this bustling picture book for fans of Mighty, Mighty Construction Site . Wearing their hard hats, safety goggles, and work boots, a team of toddlers are busy building away. Using excavators, shovels, and bulldozers, they are hard at work making their perfect playhouse blueprint come to life. Jaunty rhyme perfectly complements the playful and bouncing illustrations in this kid pleaser. "A picture book custom-built for construction-site-obsessed tots . . . Guest's rhyming text imagines a workforce of toddlers heading out to work at a construction site. Nakata's cherubic, pudgy, diverse cast of characters is clearly up for the job . . . A dream-come-true building book for babes in arms." — Kirkus  Elissa Haden Guest is the award-winning author of numerous children&;s books, including Bella&;s Rules and the Iris and Walter series.
