Recent scientific research supports the benefits of signing with your baby. Parents and teachers who participate in sign language studies say they experience reduced frustration, stronger bonds with their babies, and that their children have an increased interest in books. signing children also outperformed non-signing children in comparison after comparison, including language development and IQ. Additionally, signing children tend to learn to speak sooner, and by age two they have a vocabulary of 50 more real words, on average, than their non-signing counterparts. In the same way that crawling seems to stimulate a child's interest in walking, signing seems to provide an excellent bridge to verbal communication.
