More than 7 million children ages five and under receive their primary child care experiences in homebased child care (HBCC), nearly double the number of children in center/school-based care (3.8 million). Home-based child care is particularly important in the current COVID-19 health emergency. As many center and school based programs have closed in response to COVID-19, reliance on home-based childcare has increased, particularly for the essential workforce, who rely on care during nontraditional hours, such as evenings, nights, and weekends. Currently 50% of child care centers report they are completely closed, compared to 27% of family child care homes. To sustain this care option for millions of families, we commend states for their rapid response support to date and encourage states to create comprehensive plans to meet the needs of home-based child care providers. This Resource Guide seeks to highlight the value of home-based child care, the key challenges providers are facing today, and how states can take action to support home-based child care through the COVID-19 crisis and beyond.
