Social media web 2.0 technologies can be adopted as an inclusive method to assist children in enhancing their quality of education for the Sustainable Development Goals (e.g. SDGs 4 and 17). Social media technologies have been documented as low-cost, synchronous, and convenient methods to assist young children, parents, and early childhood (EC) teachers in communication and collaboration. However, few researchers have explored the potential usage of social media tools in enhancing children's physical activities in the early years, particularly during the pandemic period. This article uses the example of WeChat Sports, one of the most famous children's games supported by social media web 2.0, to explore the benefits, challenges, and potentialities of using them in ECE. This research uses semi-structured interviews to gain a deeper understanding of the attitudes and perspectives of EC teachers and parents on the potential usage of social media technologies in supporting children's physical activities. The results reveal that most participants had a good understanding of using scientific methods to assist children's physical development, however, they expressed concerns on children's health, privacy, and formal learning in terms of overexposure to social media technologies. Suggestions and implications are also provided for both social media application developers and educators in future research studies.
