In 2018, ZERO TO THREE set out to explore the topic of mindfulness to learn what the research says about mindfulness in parenting and caregiving through a comprehensive literature review. Through focus groups and a member survey, we also asked early childhood professionals about how they are using mindfulness in their work, and their hopes for integrating mindfulness further. The resources offered here were developed to share what we have learned from the research and the field, and represent the beginning of our effort at ZERO TO THREE to increase understanding of how mindfulness can support early childhood development.
