FPG’s Desiree Murray and Duke Center for Child and Family Policy’s Katie Rosanbalm co-authored these free snapshots for practitioners and educators to use for each of six developmental phases. Each snapshot provides a review of key concepts; a listing of the skills developing in that phase; an image of how co-regulation looks in that phase; a review of lessons learned about interventions to promote self-regulation; key considerations for promoting self-regulation in that phase, and more.
