Studies on single parenthood in terms of parenting are important and urgent because most studies only position parenting and its correlation with child development. This study aims to analyze in depth the meaning and construction behind the parenting style of single parents and to examine the social adaptation process experienced by children when interacting in early childhood education units. The researcher used a qualitative approach with a phenomenological method. Data were collected through in-depth interviews with three single parents and two teachers at RA An Nur Baruga in Kendari, supplemented by participatory observation of children's social interactions in early childhood education units. The results of the study found that the meaning of single parents' parenting styles focused on strategies to cope with stress and challenges faced in parenting, thereby building resilience in managing their role as caregivers. This means that parenting is influenced by coping strategies to life pressures, such as financial conditions and limited time for parenting, while parenting practices tend to prioritize early independence and responsibility for children in carrying out their activities. Meanwhile, the process of children's social adaptation in PAUD units is more dynamic and influenced by the level of children's emotional regulation, educator support, and the quality of interactions among children in PAUD units. The implications of these research findings recommend the need for partnerships between PAUD and families, as well as peer support programs, to provide protection and foster the social-emotional development of children with single parents.
