► The engagement of children with disabilities in childcare was observed across activity types. ► Level of engagement was higher during free play and routines. ► Children with disabilities were more actively engaged during routines and more passively engaged during group activities. ► Level of adult interaction was comparable across activity types but interaction with peers more frequent during free play. ► Children with ASD engaged less and interacted less with peers in free play than children with other disabilities. The engagement and adult and peer interaction of 37 young children with a range of disabilities was measured in free play, group, and meal-routine activities in inclusive childcare settings. A significant effect for activity type was found for total engagement, active engagement, and passive engagement, with the children being more engaged in free-play and meal-routine activities than group activities. Free-play and meal-routine activities provided better opportunities for active engagement than did group activities, but children were more actively engaged during meal-routine activities than during free play. Passive engagement was more commonly observed during group activities. Children interacted more with their peers during free play. When children with a diagnosis of autism spectrum disorder were compared with children with other disabilities, they were found to be significantly less engaged during free play and interacted less with their peers. The implications of these findings for inclusive practice in childcare settings are discussed.
