From the duo behind the Baby Loves Science series comes a STEM first concepts spinoff perfect for little scientists discovering their own amazing powers! Accurate enough to satisfy an expert, yet simple enough for baby, this book explores the world of sound-what it is, how it's made, and how Baby hears it. Baby also learns that some ears use technological help, and some people use ways other than sound to communicate. 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!
