I think people are confusing gentle parenting (Ridiculous name) with permissive parenting. Permissive parenting is neglectful parenting.
I also think there is a distinction to be made between authoritarian and parenting that imposes clear boundaries and enforces clear expectations. The former is abusive, and the latter good parenting. A parent who parents a child with empathy, respect, good communication, and clear boundaries can also be a parent who instils respect, and enforces good behaviour actively over reactively.
I work with LAC who have experienced authoritarian parenting and others neglectful permissive parenting. I've yet to find kids in care who have experienced 'gentle parenting'
But the main causes of behaviour is the failure of values, inequalities, poverty, the effect of trauma and stress generationally, selfishness, prevalence of narcissistic behaviours, parental stress, and I focus on adults and adult life. It isn't caused by being present, child focused, gentle, empathetic, responsive and responsible.
So many parents here on threads throwing their arms in the air "I can't cope" I want SS to help, the school are not doing enough.....yada yada and so much sympathy poured upon the adult.......its shocking.
