As the youngest of 6 in a supremely dysfunctional family, I experienced abuse from all except the eldest, who became my emotional mother and Safe person by 8yrs of age and launched into the world that same year. Every time an older Sibling left home, I became more at risk. Outside my home, the Only 'Safe place', turned out, was just A little Less dangerous because noone was assaulting my body. In addition I experienced several significant traumas outside my home, outside the range of the ACEs questionnaire.
Are there any Studies or Theories being explored around how Sibling abuse or trauma outside the home, in addition to the standard ACEs scale, impacts Child Development and CPTSD?
