A baby and a dog discover gravity in this appealingly illustrated, developmentally inappropriate book.This and Baby Loves Coding are the latest offerings in the Baby Loves Science series of board books. These cute but overzealous attempts to create STEM students from children fresh from the womb seem aimed more at pushy parents than at doctoral candidates in diapers. Previous volumes have featured toddlers who love quarks, aerospace engineering, thermodynamics, and quantum physics. The contents of this book have been vetted for scientific accuracy; one wonders whether the creative team also vetted the practical value of teaching preschoolers to parrot answers to questions they're ill-equipped to pose or indeed comprehend: "Why does a noodle fall? / Because of gravity!" Babies will have observed the central action this book presents—the fall to the floor of some tidbit from their highchair trays—over and over, but does "When Baby drops something, the earth pulls it down" adequately describe the phenomenon? For a toddler audience, even simple explanations of the science in this book require more exposition than board books allow and raise more questions than they answer. "Everything is made of matter. The amount of matter is called mass." OK, what is matter? And if gravity makes spaghetti fall to Earth, why does it make the moon go around it? The baby has brown skin and tightly curled black hair.Good intentions gone wrong. (Board book. 1-4)
