Parents who are plurilingual have a portfolio of assets they can use to support the language development of their children. This portfolio of assets is positioned as a strength that parents bring into their partnership with early childhood educators. However, not all parents who are plurilingual have the same assets in their language portfolios. Our study, using case studies of parents who have multiple languages and a desire to raise their children with more than one language, demonstrates that previous parental experiences with multiple languages, and intra-familial support for multiple languages combine to impact on parental language strengths and the expectations parents have of early childhood professionals. To build effective partnerships with parents, early childhood professionals need to understand the assets in parental language portfolios.
