Early home literacy experiences, including parent--child book reading, account for a significant amount of children's later reading achievement. Yet there is a very limited research base about the home literacy environments and experiences of children with cognitive disabilities. The purpose of this study is to describe findings from a Web-based survey of home literacy environments of young children with Down syndrome. Respondents (n = 107) were mostly mothers; a majority were well educated. Findings suggest that respondents gave literacy a higher priority than reported in prior research on children with disabilities. More than 70% of respondents had 50 or more children's books and also had literacy materials including flash cards, magnetic letters, and educational videos or computer games. Most parents read to their children and used these literacy materials 10 to 30 min per day. Respondents reported that their children had reached many important early literacy milestones, and they also described having relatively ambitious lifelong literacy goals for their children. Important implications for research and practice are discussed. (Contains 5 tables and 1 figure.)
