This study focuses on the everyday morning microtransition in childcare centres that involves child-parent separation. This moment involves the contemporary presence of the child, caregiver and parent in the day-care centre. This coexistence is considered extremely relevant and full of important meanings for the interactive patterns they will build together and for the children's development. In order to explore this topic, 4 children (mean age 26 months), their parents and 3 caregivers were observed in a day-care centre for 3 months, for a total of 20 video-observations. Using a triadic perspective and microanalytic analysis method, the observations were analysed through the application of the triadic interaction analytical procedure. The results showed different interactive sequence processes to the microtransition from the parent-child interaction to the child-caregiver interaction. However, various types of interactive patterns emerged in relation to the child-parent-caregiver interaction, which show the active role of all the members in the co-construction of the interactive dynamic.
