Hi Kerry, Sounds like you are working on a big project to help children and families! We need that! Have you considered a Reflective Consultation? I have my PhD in clinical psychology with a Parent Infant Mental Health Specialization and taught child development at the college level 13 year prior to getting my PhD. Ed Tronic was one of my teachers.
In a very high poverty, rural and urban county we implemented a Reflective Consultation Project with parents and infant/toddler caregivers from the babies childcare programs. It was highly successful in providing some of the protective factors needed to build resilience. The best intervention for babies is supporting their Mama (& papas +caregivers). This process is very therapeutic and educational. I trained ECE professionals to be the Reflective Consultants, then I provided Supervision and support for them after they had regular meetings with parents and outside caregivers (could be any groups). This work is deeply rooted in trauma & resilience research and of course infant-parent mental health best practices. Let me know if you'd like to connect more about this. 
Sounds like you are doing amazing work!
