The first 5 years of life are extremely important for language acquisition. We make connections, learn to process and express ourselves all while learning about the world around us. Communication is vital to our physical and mental well-being. Without language how can one advocate for themselves, or expect to have their emotional or physical needs met at all? Language Equality and Acquisition for Deaf Kids (LEAD-K) is a national effort to pass state legislation ensuring that children who are Deaf or Hard of Hearing have a strong language foundation and kindergarten readiness. Missouri passed House Bill 447 in August 2023. This Bill lists specific requirements and goals. Please see the MO Connections link for a full list of Child Milestones as well as resources for parents.
