This study examines how an unequal access to culture begins in early childhood and the role of art museums in addressing. Early cultural experiences shape cognition, emotion, sensitivity, and expression, yet access in Korea is limited by regional and socioeconomic disparities. To explore this issue, interviews with seven public childcare teachers in Seoul were conducted, and museum cases were analyzed, including MoMA’s Family Story Time, the National Museum of Modern and Contemporary Art’s Child Space, and the Seoul Metropolitan Office of Education’s Community-Linked Museum Program. Results show that art museums enhance accessibility and emotional engagement through free, integrated programs combining appreciation, experience, and sharing. In contrast, childcare settings remain fragmented and outcome- focused, with unequal infrastructure restricting opportunities. The study concludes that art museums can function as open educational spaces for young children, requiring stronger collaboration with childcare institutions, balanced infrastructure, and integrated policy support.
