This document discusses ADHD from a bioecological perspective using Bronfenbrenner's ecological systems theory. It argues that changes in American parenting practices over the last century, including decreased breastfeeding rates and earlier weaning ages, have disrupted the mother-child relationship and altered child development. Specifically, it suggests that reduced breastfeeding has decreased oxytocin levels in mothers and altered their perceptions and behaviors towards their children. This framework challenges the current medical model of ADHD by arguing that normal child behaviors have become pathologized due to changes in family and cultural systems over time.
