This article reviews how a receptive, bilingual four-year-old increased her Spanish productive-language skills over five weeks as she engaged in Spanish-language play sessions with bilingual peers. The data show her growing participation in group verbal interactions along with her growing production of her weaker language. In addition, a microanalysis of play sessions illustrates the techniques employed by the four-year-old's playmates to scaffold the linguistic production of the child's weaker language in sociodramatic play. The author concludes that the study has implications for parents who wish to provide their children with opportunities to develop or maintain more than one language. (Contains 4 tables and 1 figure.)
