Teaching Signs for Baby Minds™ teaches you how to communicate with your baby or toddler before he or she can speak! These fun, easy-to-follow DVDs with reinforcing flashcards show you how to use American Sign Language (ASL) to teach your baby how to communicate wants, needs, and observations. Teaching your baby sign language is a gift the two of you can share throughout your lives. Researchers have found a 12-point difference in the IQ scores of babies who sign and those who do not. This is a huge difference in IQ scores! Preschoolers who learn to sign also test significantly higher on the Peabody Picture Vocabulary Test, a common assessment of verbal ability used to aid school placement.
