This article presents autoethnographic short stories that describe an early childhood education and care (ECEC) centre director's work for one year in a municipality in Finland. The purpose of this article is to provide a glimpse into what it is like to enter into an ECEC director position and live everyday ECEC life with economic data that are produced by frequently fluctuating child-staff ratios. This study contributes to a better understanding of the transformational implications of datafication by providing insight into affective interrelations held together by economic aspirations. It shows that datafication is a powerful tool to affect and to be affected in the female-dominated care work of ECEC. The study highlights the possibilities of using an autoethnographic analysis to recognise how data affect the body in data dominated ECEC and how to utilise this very recognition as resistance.
