This research project explores the impact of singing on babies during their daily transitions into a nursery setting, with focus on emotional security, routine adoption, and caregiver child relationships. Rather than examining the initial induction into nursery, the study investigates how singing supports infants as they arrive for their regular sessions, often moving from home or other environments into the nursery space. Qualitative methodology was employed, using semi structured interviews with early years practitioners and non-participant observations within a baby room in a single nursery. Data was analysed thematically using the constant comparative method, which revealed several recurring themes. The findings highlight that singing plays a significant role in promoting emotional regulation, enhancing communication, and strengthening the bond between babies and their key persons. Singing familiar songs helped babies feel secure and soothed during arrival and daily transitions, while lullabies and action songs contributed to language development and Co regulation. Practitioners consistently describe singing as a simple yet effective tool to support babies well-being and settling in process. Although the study was small scale and limited to one setting, it provides valuable insights into the practical and emotional benefits of incorporating singing into daily routines. The research suggests that singing is not only enjoyable but also an important strategy for nurturing secure, resilient, and emotionally supported young children.
