Early childhood teachers, administrators, and program staff need to have factual information so that they can create welcoming, inclusive, and strength-based environments that are responsive to the unique needs of young children and families experiencing homelessness. This book was written with this goal in mind and, specifically, to support early childhood teachers and program leaders to learn about the following: - the number of young children and their families who experience homelessness nationally and across California and its underlying causes; - recent federal and state laws, policies, and entitlements that address child and family homelessness; - the impacts that homelessness can have on young children's health, development, and ability to learn; and - effective strategies and trauma-informed practices that can be implemented in early childhood programs to support children and their families experiencing homelessness.
