Designed to help students and educators make critical theory-to-practice connections, this essential volume provides a deep yet accessible approach to infant and toddler language and literacy education. Centered around four foundational topics—language, interaction, and play; language and culture; multilingualism; and early literacy—each section starts with a chapter breaking down the research and theory, followed by two practice chapters, from both leadership and teacher perspectives, that illustrate key concepts across a range of infant-toddler contexts. Ideal for students in early language and literacy courses as well as programs on infant-toddler development, this critical resource helps readers thoughtfully and practically bring multilingual and multiliterate development to the infant and toddler years.
