Raising bilingual children opens children to tremendous opportunities. At the same time, families often experience challenges in raising their children bilingually. Some common questions are what works and what doesn't work to raise bilingual children, how can parents motivate children to speak a second language, and how much of a second language do children need to become proficient? Do parents need to be fluent in a second language for a child to acquire the language? What does the science say about these questions? This talk will focus on how bilingualism can be expected to impact a child’s development, as well as some of the common challenges that parents face and on research-based strategies to support bilingualism in young children.
