Using sign language as speech develops and is fine tuned will help young children to play with language and it will help them clarify communication attempts. As any parent to a toddler knows, if you can avoid frustrations by being clearly understood, it's a good thing!
Parents are amazed at what babies can say!
We all know that communication is an essential component of a child's development. Infants are able to make sense of our complex world long before they can talk. Do you wish your baby could tell you such things as "I'm hungry," "I'm thirsty," "I have an earache" before they can speak? Parents are amazed how much earlier a hearing baby can communicate with their hands using American Sign Language.
