© 2020 Human Kinetics, Inc. Background: In December 2018, the South African 24-hour movement guidelines for birth to 5 years were released. This article describes the process used to develop these guidelines. Methods: The Grading of Recommendations Assessment, Development, and Evaluation-ADOLOPMENT approach was followed, with some pragmatic adaptions, using the Australian guidelines for the early years as a starting point. A consensus panel, including stakeholders in early childhood development and academics, was formed to assist with the development process. Results: At a face-to-face meeting of the panel, global and local literatures were considered. Following this meeting, a first draft of the guidelines (including a preamble) was formulated. Further reviews of these drafts by the panel were done via e-mail, and a working draft was sent out for stakeholder consultation. The guidelines and preamble were amended based on stakeholder input, and an infographic was designed. Practical "tips" documents were also developed for caregivers of birth to 5-year-olds and early childhood development practitioners. The guidelines (and accompanying documents) were released at a launch event and disseminated through various media channels. Conclusions: These are the first movement guidelines for South African and the first such guidelines for this age group from a low- and middle-income country.
