Imagine 2-year-old Malek, growing up in an Arabic-speaking home, entering childcare for the first time. At home, language carries feeling, memory, and family connection. In care, it may be the first time he learns that only one language is recognized and that the other must stay behind. As New York City expands care for 2-year-olds, the public conversation has largely centered on key logistics: seats, speed to implementation, and salaries for home-based providers. Another fundamental question is how this expansion will shape children’s relationships to language, community, and belonging, especially for multilingual families whose experience with formal education is associated with estrangement from their home culture and language.

For decades, growing up with more than one language was wrongly framed as a deficit; it was once described as “semilingualism.” A large body of research has documented the social, communicative, and educational benefits of multilingualism, including stronger connections to family and community, and broader cultural and economic opportunities. The evidence is clear: Multilingualism is an asset, not a liability, supporting not only how children learn, connect, and participate in the world, but also adding to their professional pathways in the future.

Anyone who works in education knows the pattern of language loss that begins when a child enters the school system. Over time, heritage languages begin to fade, a loss that is often normalized as an inevitable part of schooling and assimilation. Research, including our own, shows that heritage language attrition follows a predictable pattern when children enter settings where one language dominates socially and institutionally, causing the dominant language to expand at the expense of the other. This is not only a cultural issue; it is foundationally developmental. Sustained exposure to both languages supports more stable language development, while early shifts away from the heritage language can disrupt that balance.

In one of the most linguistically diverse cities, we continue to reproduce monolingualism despite overwhelming evidence of the benefits of multilingualism. New York City’s 2-K program, with its focus on community- and home-based providers, is significant not only for expanding access, but for reshaping how early education is experienced. These programs, and their providers, who are often members of the same community as the families, offer services that are qualitatively different from formal institutional care, offering environments where language, culture, and relationships are not separated from learning, but are its foundation. They are truly a child’s home away from home.

Taken together, the expansion of 2-K home-based care can reshape how language, culture, and education interconnect as a foundation for learning.

In home-based settings, children are more likely to hear and use multiple languages in meaningful, everyday interactions with caregivers and children across ages. Care is organized around relationships and participation, rather than standardized expectations of academic performance. These are not incidental features. They are developmental conditions that support how language is sustained, how children come to belong, and how communities reproduce themselves across generations.

If supported intentionally with professional development opportunities, mentorship, and resources, these community environments could play a critical role in addressing one of the most persistent and overlooked challenges in US education: the systematic erosion of heritage languages beginning in early childhood. One proven way to enhance language development in home-based settings is strengthening the quality of adult-child interactions. In a randomized controlled trial we conducted in linguistically diverse communities, we found that babies in home-based child care vocalized far more when their providers used a program designed to strengthen relationships than did babies in the control group. We also found that the program led to reductions in background noise (such as television and other electronic sounds).

Together, these transformations in the babies’ language environment point to a simple lesson: When caregivers are intentionally supported in building warmer, more responsive interaction patterns,........
