In a 2019 review paper, the authors identified the lack of interventions designed for toddlers as a gap in the research literature (Jones et al., 2019). The authors advocated the need for more PA interventions targeting children 0–3 years of age and for such interventions to be developmentally appropriate. Our proposed pilot study was designed to address this gap. Before designing and implementing long-duration PA effectiveness studies in toddlers, it is crucial to first determine the feasibility of implementing PA interventions set within the childcare setting for toddlers. Therefore, the purpose of this pilot study was to examine the feasibility and preliminary efficacy of a 10-week program implemented by providers and researchers to alter toddlers’ time spent in total PA [light to moderate-to-vigorous PA (MVPA)] during the childcare day.
