Most good parenting involves knowing when to step back—but sometimes parents need to take charge. Duncan explains the idea of a “train track moment”: a situation where safety is at stake and there isn’t time to negotiate, deliberate, or worry about making your child unhappy. He discusses how to distinguish healthy noninterference from necessary intervention, and why decisive action during a genuine crisis is part of being a good leader.

Duncan talks with occupational therapist Val about how autism is recognized and diagnosed, what experienced clinicians notice that formal testing may miss, and why some children—particularly girls—can be difficult to identify. They also explore conditions that can look like autism, why diagnoses have risen so dramatically, and where the evidence ends and clinical experience and opinion begin.

Part of growing up is learning to take responsibility—for everyday tasks, decisions, mistakes, and ultimately your own life. Duncan discusses why parents often transfer responsibility too slowly, why diagnoses and developmental challenges should be treated as factors rather than automatic excuses, and why children need opportunities to try, fail, and try again. The goal isn’t responsibility for its own sake: with greater responsibility comes greater freedom, confidence, and independence.
