At just six-to-nine months old, babies grasp the concept of vocabulary and realize that objects have names. However, with little vocal control, they can’t form words with their mouths — but they can with their hands! Learning to sign helps ease the frustration babies experience when they can't communicate their needs to parents. Part of the Amazing Baby series, the book is perfectly-sized for tiny hands and mouths to explore. In her engaging instructions, Katie Mayne teaches parents how to understand their little ones using simple sign language, starting with signs for "milk," "food," "drink," and progressing to instructional signs like "look" and beyond. Including a tabbed index, this is an ideal book for new parents to share with their babies.
