This specialized course tailored for speech-language pathologists (SLPs) will delve into the concept of baby sign language (BbSL). BbSL involves simplified gestures or signs used as an alternative augmentative communication method with pre-verbal infants. Attendees will explore the scientific basis behind how BbSL influences language development in both neurotypical and neuroatypical infants, enabling clinicians to offer tailored recommendations to parents, caregivers, educators, and healthcare professionals regarding its impact on language growth. Additionally, we will examine the evolving relationship between BbSL and early intervention, as well as its role as an alternative augmentative communication strategy.
