Chiming in that Dr. Perry's NMT is a great model too - but is more focused on child's trauma - and need for helping child to regulate and build relationship than the attachment work for the family -- Perry's model and his "five Rs" could and should be integrated into any attachment/trauma work therapists and other trauma-informed professionals are doing -- the movement and sensory components of this (and TBRI, Theraplay and others) is critical.
