Baby sign language is the use of manual signing allowing infants and toddlers to communicate emotions, desires, and objects prior to spoken language development.[1][2] With guidance and encouragement, signing develops from a natural stage in infant development known as gesture.[3] These gestures are taught in conjunction with speech to hearing children, and are not the same as a sign language.[4] Some common benefits that have been found through the use of baby sign programs include an increased parent-child bond and communication,[5] decreased frustration,[5] and improved self-esteem for both the parent and child.[6] Researchers have found that baby sign neither benefits nor harms the language development of infants.[2][7][8] Promotional products and ease of information access have increased the attention that baby sign receives, making it pertinent that caregivers become educated before making the decision to use baby sign.[2][8]
