What scientific research supports the idea of signing with babies?
Research in this area is continuing today at Ohio State University, see the following article. A longitudinal study was conducted at the University of California at Davis by Drs. Linda Acredolo and Susan Goodwyn. The study, which followed babies through their eighth year, indicated that signing with babies has many benefits including a strengthened parent-child bond, increased interest in books, enhanced verbal language development, and higher IQs.

Also, I strongly recommend reading Dancing with Words: Signing for Hearing Children’s Literacy, by Marilyn Daniels.
