While physical development goes hand in hand with cognitive development, we can see how a child's motor skills can impact their cognitive ability and vice versa. But how does sign language impact a child's motor ability?
It should be noted that the correlation between motor skill and language development is a complex and multifaceted process and similar to our initial post “A Baby's Language Development,” not all babies follow their milestones exactly as purported. However, the acquisition of a new motor skill, like sign language, has been shown to initiate developmental cascades that influence subsequent language learning in developing infants. In short, learning how to utilize sign language with your baby can positively influence their ability to not only jumpstart their motor skills development but also increase their ability to learn in the future.
