Given enormous global challenges, alongside nurturing children's creativity, professional creativity has perhaps never been more vital ([0100] and [0190]). This paper considers how a small, qualitative, co-participative study in an inner city children's centre, explored practitioner perspectives and practice related to creativity understood as possibility thinking. This research builds on previous studies that have documented possibility thinking and analyses the nature of possibility thinking manifest in child-initiated immersive play triggered by practitioner-placed provocations, and pedagogical strategies which foster this.
