A multiple case-study design was used to explore the spontaneous play of three toddlers with disabilities as it emerged in the course of everyday activity in the home. Children were observed at home playing independently and with their mothers. Data consist of videotaped naturalistic observations in the children's homes and mothers' perspectives of their child's play obtained in semi-structured interviews. There was a great deal of similarity in the playful behaviour of toddlers and their mothers. Toddlers were active players throughout all daily routines and their play reflected their developmental level. Mothers actively supported their children's initiative and engagement in play and they spoke of play as a highly valued behaviour. Some qualitative differences were noted in child and mother-child play, which seemed to relate to the nature of the child's disability and developmental level. Further study of the play of young children with disabilities in naturalistic settings and ways that mothers and other caregivers value and support child play is recommended. (Contains 2 tables.)
