In terms of parenting I did a systemic social work course and it's amazing how much you learn from your family of origin. Consciously and unconsciously. You learn how to do life really, we all have family scripts that teach us how to do traditions, roles, communicate, resolve conflict, how we view ourselves and others etc. Think about how much the way we do Christmas, birthdays, meal times etc is learnt from our childhood! Our parents teach us how to parent and give us a blueprint for life, from small stuff like who does the food shopping to huge stuff like how to conduct arguments or attend school and work.
If you received poor parenting you can either replicate (do what they did), correct it by doing the exact opposite (completely reject their way) or improvise and parent intuitively and come up with your own way. It's a choice and you are responsible for your choice.
Not a lot of us are taught to 'do' emotional regulation well. Most of us do reflexive Stimulus > Response. Someone or something stimulates an emotional response and we react with x behaviour. When you start to be self aware and reflect on your behaviour you start to do Stimulus > Pause > think about why you feel that way and want to respond that way > think if that's a healthy response or a trauma/unhealthy/unconscious response> CHOOSE a response.
US, BB (and maybe silent uncle) seem to have zero self awareness or self control, self reflection or sense of self. Look how they are so emotional in court. It's just ego centred drama, with their 'show' in the centre. The basic lack of human empathy for a tiny child like Sara, and I suspect the other kids shows how broken they are. They can't control themselves or their lives and they are like ego based, undeveloped, angry, aggressive toddlers in adult bodies. They are beyond pathetic. Unhealed, unaware and unsympathetic as people
