Boone County Project LAUNCH is offering free developmental screenings for children who are 2 months to 5 years old. Parents will complete an "Ages & Stages" questionnaire and then meet with a specialist who will explain more about childhood developmental stages. Results can help you monitor your child’s motor skills, language development, problem solving ability and social-emotional skills. Developmental screening can help ensure that a child is on-track for school success. Children from 2 months to 5 years old and parents.
