The play needs of under threes is an under-researched area. In this study, 100 parents and carers were surveyed regarding their visit to a children's museum with a child under three. Using a play taxonomy and observation schedule devised for the study, 50 toddlers were also observed playing with the museum exhibits. The findings showed that whilst there were many reasons for the visit (including play), it was not with the purpose of learning. However on reflection, it was one of the perceived benefits. There were significant differences in types of play engaged in; younger toddlers engaged in more ego play and older toddlers engaged in more pretend and role play. Also, children enjoyed playing and learning with all exhibits despite being arranged for particular age groups. These findings and the tools used in the study will be of interest and use to early years educators and museum educators.
