Now available in Spanish bilingual editions, this best-selling series offers big, brainy science for the littlest listeners.
Accurate enough to satisfy an expert, yet simple enough for baby, this clever board book explores the ups and downs of gravity. When baby drops food from a high chair, why does it fall? Beautiful, visually stimulating illustrations complement age-appropriate language to encourage baby's sense of wonder. Parents and caregivers may learn a thing or two, as well!
