Book excerpt: BABY SING & SIGN is a wonderful, sensory-rich way to teach and practice key sign language vocabulary with hearing babies and toddlers. Sign language is a proven way to jump start language and provide little ones with important communication skills to express their wants and needs before they are able to speak. We use the child's preferred activities -- music and play -- to engage families in language learning. The program is great "baby brain food" and fun and easy for the entire family. The Parent Guide gives families all the tools they need to be successful teaching baby sign and supporting their child's emerging language.
