IX.Dissemination The Committee recommends that States parties disseminate this general comment widely within Government and administrative structures, to parents, other caregivers, children, professional organizations, communities and civil society at large. All channels of dissemination, including print media, the Internet and children’s own communication means should be used. This will necessitate translation into relevant languages, including sign languages, Braille and easy-to-read formats for children with disabilities. It also requires making culturally appropriate and child-friendly versions available.
