“…Although there are natural variations in maternal care, extremely stressful circumstances can push these normal variations into abusive, neglectful, and trauma-associated maternal care; these can engender a disordered attachment, which is associated with a decreased regulatory capability in the caregiver (Carlson, Hostinar, Mliner, & Gunnar, 2014; Hostinar, Sullivan, & Gunnar, 2014).
