The content on the ABCMouse website is created for children in preschool through kindergarten, and it's safe and age-appropriate. The website is a subscription service, but it has no links to other sites and customers don't have to worry about pop-ups or links that their young children might follow.
The site is set up so that children can use the site with or without their parents, depending on their personal skill level. The curriculum for the site was developed by a board of early childhood education experts. The website offers a list of these experts in their "about us" section of the site for parents who wish to learn more about the people behind the scenes of the site.
