Baby Sign Language is a method of communication that uses hand gestures to help infants express their needs and feelings before they can speak. It involves teaching simple signs for common words like "milk," "more," and "all done." This can reduce frustration for both babies and parents by allowing babies to communicate their desires. Parents typically start teaching Baby Sign Language around six months of age, as this is when babies begin to develop motor skills. Research shows that using signs can enhance language development and strengthen the bond between parents and their children, making it a valuable tool for early communication.
