“Lift your legs up and down. / Twirl your hips round and round. / Wiggle, waggle to the sound. / And move to the beat.” Irresistible rhythm and catchy language will have babies and toddlers bouncing to this delightful read-aloud. The story shown in the illustrations follows children gathering with cake, gifts, and balloons for a birthday celebration. A recurring chorus of “Shake, shake, shake it, baby! / Come and dance with me!” invites even the youngest listener to join in on the fun. Heavyweight pages will hold up to vigorous repeat readings. Highly Commended, 2009 Charlotte Zolotow Award. (Ages birth–3)
