Parents have accessed websites, online discussion forums and blogs for advice, information and support since the early days of the World Wide Web. In this article, we review the literature in sociology and related social research addressing the ways in which digital media have been used for parenting-related purposes. We begin with the longer-established media of parenting websites, online discussion forums, blogs, email, mobile phones and message and video services and then move on to the newer technologies of social media and apps. This is followed by a section on data privacy and security issues. The concluding section summarises some major issues arising from the review and points to directions for further research.
