Definition & Meaning of "baby sign"

What is "baby sign"?

Baby sign refers to a system of simplified signs or gestures that parents and caregivers teach infants to help them communicate before they can speak. This method often incorporates signs from established sign languages, adapted for young children, allowing them to express their needs and feelings, such as hunger, thirst, or discomfort, through gestures. Baby sign can enhance communication between caregivers and infants, reducing frustration and improving understanding during the preverbal stage. Research suggests that using baby sign may also support language development, as it encourages children to engage with language and promotes early vocabulary acquisition.
